I'm very new to nodered (what a huge world to discover!)
I come to my 1st issue....
I would like to do something simple,but I cannot figure out how to do (even based on http://noderedguide.com/node-red-lecture-6-example-6-7-multiple-inputs-on-a-function-node/)
let's me explain the situation:
I would like to get the state of a tasmota sonoff switch as an answer to a telegram message.
Let's image I sent on my phone "light?" by telegram...I wish to received "on" or "off".
good point is that I have on mqtt a retained "stat" topic from the tasmota, so I can know anytime what is it's state.
So my idea was to draw:
- an MQTT input node (with the relevant "stat" topic)
- a telegram receive node.
and join both their outputs on same "function" node...
and here I'm stuck...the documentation talk about "topics"....ok for mqtt input...but telegram does not have topic?
