I have installed node-red-contrib-telegrambot, setup a bot on telegram, got a bot token and it is basically working. I can send messages from phone and pick them up in node red and vice versa. However, when I use the http POST method to send a message, for example using curl --data "chat_id=<id>&…

I do know that you cannot link bots together in Telegram and it may be that you are hitting that issue.

Perhaps I am missing something fundamental in how this is supposed to work. I have only got one bot. I am going to sleep on it and see if it makes more sense in the morning.

I have done a bit more investigating, and I think I understand the problem. As I said I have created a bot and I have access to that from the telegram app in the phone and the nodes in node-red. I can also open a web browser view of the bot. If I send a message from the phone then it is picked up…

I am now thinking this is not possible. I tried making two bots and put them both into a group, connecting one NR instance to each bot. If I send to the group from the android app then both NRs receive the message, and if I send to the group from either NR then other clients receive the messages e…

Thanks for that @drmibell , I had missed that thread as I was not thinking of doing this at that point. I think I am probably going to setup a publicly accessible MQTT server and solve the problem that way.

This is what I said before. You cannot make two bots talk to each other because it is considered a security risk, quite possibly a performance risk for the platform too - imagine two runaway bots having a rapid "conversation". Using the API is a bot. It is annoying of course. You might be able to …

Yes, what wasn't clear from the docs was that you can't use the send message api to send messages to a bot (from one NR instance for example) and then receive the messages from that same bot in another NR instance. Which isn't two bots communicating as there is only one bot.

I was able to use 2 bots by adding them both to a public group. I use Tasker to HTTP Post a message into the chat via bot 1, bot 2 receive node sees the message from bot 1 in the chat and triggers events accordingly. For security, msg.originalMessage.author_signature shows who sent the message into …

OK, thanks for that. I solved my problem using a different route (publicly accessible MQTT server, protected of course).

I think that's exactly right. The question came up in a previous discussion, What is a good way for sending messages between Node-Red and your smart phone also in case the smartphone is not connected to your LAN? - #3 by TotallyInformation, and there does not seem to be an obvious way to work around it.
