@martinhjelmare Oh it's true, I've tried it with V_IR_SEND and it worked. Thank you.

Yes it is, you can move it to the home assistant subtopic

Hello everyone,

I'm trying to control with HA my A / C just to turn on and off. For this I am using the sketch of mysensors about IRSender / Receiver.

I'm starting in this wonderful world, but I've been stuck with this error for several days: Not a valid message: value must be either 0 or 1 for dictionary value @ data ['payload']

I show you an image where it is collected:
  - on the screen top left, mysgwd
  - on the screen at the top right, IDE Arduino
  - on the screen below to the left, HA log
  - on the screen below to the right, serial monitor

The code is exactly the same as the sketch. I hope to receive your advice and be able to realize this objective.

Greetings and thank you!
