OpenClaw Telegram Bot Setup Mobile 2026: How to Talk to Your Agent on Your Phone

Your OpenClaw agent lives on a server. Probably a home server, a VPS, or a Raspberry Pi tucked behind a router. You SSH in to check on it. You edit config files. You watch logs scroll by.

But you don’t want to live at a terminal. You want to send your agent a message from the grocery store, from the couch, from bed. You want to ask it a question and get an answer without opening a laptop.

Telegram is the best mobile interface for OpenClaw for one simple reason: it requires zero infrastructure. No app to install on your server. No public IP. No webhook endpoint. Just a bot token and a few lines of config.

Telegram is already installed on billions of phones. Your agent can meet you there with no additional client software, no VPN, and no port forwarding. This walkthrough will get you talking to your OpenClaw agent from anywhere in under 10 minutes.

Prerequisites for OpenClaw Telegram Bot Setup Mobile 2026

Before you start, make sure you have the following:

  • A running OpenClaw instance. This guide assumes OpenClaw is already installed and operational on your server, whether that is a home machine, a VPS, or a Raspberry Pi.
  • A Telegram account. Install the Telegram app on your phone or use the web version at web.telegram.org.
  • Write access to your openclaw.json configuration file. This is typically located in your OpenClaw home directory.
  • The ability to restart your OpenClaw gateway process after making configuration changes.
  • A few minutes and a stable internet connection.

Step 1: Create Your Telegram Bot with BotFather

Every Telegram bot is created and managed through BotFather, the official Telegram bot that controls all other bots. This is a one-time setup that takes about 60 seconds.

  1. Open Telegram and search for BotFather. The verified account has a blue check mark and the username @BotFather.
  2. Start a chat and send the command: /newbot
  3. BotFather will ask for a display name. This is what users will see. Type something like My OpenClaw Agent.
  4. Next, it will ask for a username. This must end in bot (for example, MyOpenClawAgentBot or yourname_openclaw_bot). The username must be globally unique across all Telegram bots.
  5. If the username is available, BotFather will reply with a success message containing your bot token.

The bot token is a string that looks like this:

123456789:ABCdefGHIjklmNOPqrstUVwxyz-1234567

The format is always: a numeric user ID, a colon, then a long alphanumeric string. This token is the only credential your OpenClaw instance needs to connect to Telegram on your bot’s behalf. Keep it safe.

Write down the token immediately. You will not be able to see it again through BotFather after navigating away from the message. If you lose it, you can generate a new one at any time by sending /token to BotFather and selecting your bot.

Step 2: Configure OpenClaw for Telegram

OpenClaw uses a channel-based plugin system for messaging. Adding Telegram is a matter of adding a channel entry to your openclaw.json file.

Locate your openclaw.json file. It is usually in the OpenClaw home directory or the directory where you launched the gateway process. Open it in a text editor.

Inside the file, find the channels array. If it does not exist yet, you will create it in the plugins section. Add a new channel object for Telegram:

{
  "channels": [
    {
      "type": "telegram",
      "bot_token": "123456789:ABCdefGHIjklmNOPqrstUVwxyz-1234567"
    }
  ]
}

Replace the token string with the token you received from BotFather. If you already have other channels configured (such as Slack or Discord), add the Telegram entry alongside them in the same array.

Here is what a more complete openclaw.json might look like with Telegram and Slack both configured:

{
  "gateway": {
    "bind": "0.0.0.0:8080"
  },
  "channels": [
    {
      "type": "telegram",
      "bot_token": "123456789:ABCdefGHIjklmNOPqrstUVwxyz-1234567"
    },
    {
      "type": "slack",
      "bot_token": "xoxb-your-slack-token"
    }
  ],
  "plugins": {
    "entries": {
      "openclaw-plugin-chat": {},
      "openclaw-plugin-telegram": {}
    }
  }
}

Save the file. Then restart your OpenClaw gateway:

openclaw gateway restart

If everything is configured correctly, the gateway will connect to Telegram and begin polling for messages. Check the gateway logs for a line indicating the Telegram plugin initialized successfully.

Step 3: Find Your Chat ID and Test

With the bot running and connected, open Telegram and find your bot by its username. Start a chat by clicking Start or sending /start.

To receive messages from your bot, OpenClaw needs to know your chat ID. There are two ways to find it:

Method 1: Check the gateway logs

Send any message to your bot. Then look at your OpenClaw gateway logs. The Telegram plugin typically logs the incoming chat ID for every message received. Look for a line containing chat_id or Chat ID.

Method 2: Use @userinfobot

Open a chat with @userinfobot (the official Telegram user info bot). Send any message or just click Start. It will reply with your user information, including your numeric chat ID. This ID is your personal Telegram user ID and will be the same for any bot you talk to.

Once you have your chat ID, you can use it in OpenClaw configuration to allow your bot to talk only to specific users (if your plugin supports user allowlisting), or you can use it for proactive notifications from cron jobs or alerts.

For a quick test, try sending a simple message to your bot like “Hello” or “What time is it?” Your OpenClaw agent should reply within a second or two. If it does not, check the gateway logs for errors.

Privacy Mode: Groups vs. Private Chats

Telegram bots have a privacy setting that controls what messages they can see in group chats.

Private chats (1:1): When you message your bot directly in a private chat, the bot sees every message you send. No configuration required for this. Your bot sees everything you type to it, all the time. This is the simplest and most reliable mode for a personal assistant bot.

Group chats: By default, bots in Telegram groups only see messages that explicitly mention them. A message like “hey bot what is the weather” will not be visible to the bot unless you address it as “@YourBot what is the weather” or reply to a bot message. This setting is called privacy mode and is enabled by default for all new bots.

If you want your bot to read every message in a group (for example, a team channel where the bot monitors all conversations), you need to disable privacy mode. To do this:

  1. Open a chat with BotFather.
  2. Send the command /mybots and select your bot.
  3. Click Bot Settings, then Group Privacy.
  4. Click Turn off.

You will need to remove and re-add the bot to any groups where you want it to see all messages for this change to take effect.

Recommendation: For a personal assistant where you are the only user, stick with private 1:1 chat. It is simpler, more secure, and avoids any confusion about what the bot can and cannot see.

Polling vs. Webhooks: Why OpenClaw Uses Polling

Telegram supports two methods for a bot to receive updates: webhooks and polling (specifically, long polling). They work very differently, and the choice matters for how you deploy your bot.

Webhooks: Telegram sends an HTTP POST request to a public URL every time someone messages your bot. This requires a publicly accessible HTTPS endpoint with a valid SSL certificate. This is fast and efficient, but it means your server must have a public IP or domain name, an open port, and a properly configured TLS certificate. This is a non-starter for many home server setups.

Long polling: The bot client (your OpenClaw instance) opens a connection to Telegram’s servers and asks, “Do you have any new messages for me?” Telegram holds the connection open and responds as soon as a message arrives, or after a timeout if there are none. The bot then processes the messages and immediately opens a new polling connection.

OpenClaw uses long polling. This decision is deliberate and practical:

  • No public URL required. Your server can be behind NAT, behind a firewall, on a home router, on a private VPN, or on a machine with no inbound ports at all.
  • No SSL certificate configuration needed. Telegram servers initiate nothing. Your bot only talks outbound to api.telegram.org.
  • Works on any network. If your server has outbound internet access, long polling works. Period.
  • Simpler to debug. Polling connections show up clearly in logs. If the bot stops responding, you can see whether the polling loop is running.

The only downside of polling is that it keeps a persistent connection open, which consumes a small amount of memory and a negligible amount of bandwidth. For a personal bot handling a few hundred messages per day, the resource cost is effectively zero.

Advanced Features: Voice Notes, Files, and Proactive Notifications

Telegram is not just text. Once your bot is connected, you unlock several advanced interaction modes that make mobile use far more natural than typing.

Voice notes: Telegram supports sending voice recordings in chat. With the appropriate transcription plugin configured in OpenClaw, your agent can receive a voice message, transcribe it to text, and process it as if you had typed the request. This is transformative for mobile use. You can record a voice note while walking your dog, driving (hands-free), or cooking, and your agent will understand and respond. The transcription plugin must be enabled and configured with a speech-to-text service such as Whisper or an equivalent provider.

File and image sharing: You can send files, images, PDFs, and documents of any type to your Telegram bot. OpenClaw receives the file, downloads it from Telegram’s servers, and can process it according to your agent’s capabilities. This means you can snap a photo of a whiteboard and ask your agent to summarize it, forward a PDF and ask for an extract, or share a spreadsheet and request an analysis. The bot handles file downloads automatically as long as the Telegram plugin is connected.

Proactive notifications: The connection goes both ways. Your OpenClaw agent can send you messages at any time, not just in response to your messages. This enables powerful automation scenarios:

  • Cron job completions. Set up a daily report or a monitoring check that fires at a specific time and pings you on Telegram with the results.
  • Security alerts. If your security monitoring detects an anomaly, it can send a Telegram alert directly to your chat ID.
  • System status. Low disk space, high CPU, service down – your agent can notify you immediately instead of waiting for you to check.
  • Task reminders. Your agent can ping you on Telegram for scheduled or time-based reminders.

To use proactive notifications, your agent needs to know your chat ID (as described in Step 3). The specific configuration depends on your OpenClaw plugin setup, but the pattern is generally: the agent calls a send-message function targeting your numeric chat ID.

Rate Limits: What You Need to Know

Telegram applies rate limits to bot API calls. Understanding them prevents confusing behavior where your bot appears to stop working because it is being throttled.

  • 30 messages per second: This is the global limit across all recipients. A personal bot will never approach this.
  • 1 message per second per chat: This is the per-conversation limit. If your agent has a lot to say, it must pace itself. Messages beyond the limit are silently dropped or return a 429 error.
  • File downloads: File download endpoints have their own rate limits but are generous enough for personal use. Do not write code that downloads hundreds of files in rapid succession from the same bot.
  • Group broadcasts: If your bot is in multiple groups, sending a broadcast message to all of them simultaneously will hit the per-chat limit on each group. Space out bulk sends by at least one second per recipient.

For a personal assistant bot that talks to one or two users, you will never hit any of these limits under normal use. They only matter if you are building automated pipelines that generate large volumes of outbound messages.

OpenClaw’s Telegram plugin implements basic backoff for rate-limited requests, but if you are doing custom development, handle HTTP 429 responses by waiting and retrying.

Security: Protecting Your Bot Token

Your bot token is a secret credential. It is equivalent to a password. Anyone who possesses your bot token can:

  • Send messages as your bot to any Telegram user
  • Read messages sent to your bot (if they poll for updates)
  • Modify the bot’s avatar, description, and commands (via BotFather)
  • Kick the bot from groups
  • Delete the bot entirely

Follow these security practices:

  • Never commit your bot token to version control. If you use Git, add a .env file or a secrets file and use environment variable substitution in your OpenClaw config. Many users store the token in an environment variable like $TELEGRAM_BOT_TOKEN and reference it from the config.
  • Never paste your token into a public forum, a GitHub issue, a pull request, or a chat room. A single copy-paste mistake can expose it to the internet permanently.
  • Restrict file permissions on your openclaw.json file. Set it to 600 (owner read/write only) on Linux: chmod 600 openclaw.json.
  • Use a dedicated bot for your personal agent. Do not reuse a token from a public bot.
  • If you suspect your token has been exposed, revoke it immediately by sending /revoke to BotFather and selecting your bot. Then generate a new token with /token and update your config.
  • Monitor your bot’s activity. If you receive messages you did not send, or if the bot’s behavior changes unexpectedly, assume the token is compromised and revoke it.

The Telegram Bot API itself is encrypted end-to-end between your server and Telegram’s servers. The risk is not in transit – it is in storage and handling of the token on your side.

Troubleshooting Common Issues

Bot does not respond to messages

Check your OpenClaw gateway logs. The most common cause is a missing or incorrect bot token. Verify that the token in your openclaw.json matches exactly what BotFather gave you, including the colon and all characters. Also confirm that the gateway process restarted after you saved the config change.

Bot was working and suddenly stopped

Check if your internet connection is operational. If the server lost connectivity and reconnected, the polling loop may need a gateway restart to re-establish. Also check whether the bot token was revoked or regenerated. If you requested a new token from BotFather, the old one stops working immediately.

Messages arrive very slowly or in bursts

Long polling has a default timeout of 30 seconds on the Telegram side. If the polling connection is dropping and reconnecting frequently, messages may appear to arrive in batches. This is usually a network stability issue. If the problem persists, check for firewall rules that might be interfering with outbound connections to api.telegram.org on port 443.

Bot sees some messages but not others in a group

This is privacy mode at work. Bots in groups only see messages that mention them by username. See the Privacy Mode section above for how to disable this if you want the bot to see all group messages.

Cannot find chat ID in logs

The chat ID is logged by the Telegram plugin when a message is received. If you do not see it in your logs, check the log level. Set verbose or debug logging temporarily to ensure the incoming message metadata is printed. Alternatively, use @userinfobot as described in Step 3.

Voice messages are not being processed

Voice message transcription requires a separate plugin or service configured in OpenClaw. The Telegram plugin itself delivers the voice file; transcription is handled by a downstream component. Check that your speech-to-text plugin is installed and configured with valid credentials (for example, an OpenAI API key for Whisper).

Gateway fails to start after adding Telegram config

If the gateway process crashes or fails to start after you add the Telegram channel, the most likely cause is a JSON syntax error. Validate your openclaw.json with a JSON validator. A missing comma, an extra comma, or an unclosed bracket will prevent the file from parsing correctly. You can validate locally with: python -m json.tool openclaw.json.

Bot sends “429 Too Many Requests” errors

Your agent is hitting Telegram’s rate limits. Reduce the frequency of outbound messages. If the agent sends multiple rapid replies (for example, processing a queue of tasks), introduce a one-second delay between messages to the same chat.
