I'm trying to use telegram to advise a high temperature from my sensor and I have two doubts. Firstly I need to do a function to filter out temperatures up to 30. Secondly in Telegram I can't solve the problem about ChatID, I put the firsts numbers of my token and it doesn't work, after it I send a message from Telegram to my Node-Red and I copied the chatID, but not works.
Somebody knows how I can solve that? I attach an image with explanations but the newest Telegram explanation is in this text.
