@tekka Right now, I am looking where your files are different from mine. I do not understand where I went wrong. perhaps I should also delete the other files that make creates, not just the hex. Either way. A lot of thanks.

@adfx Thanks for checking. I read once a blog/page about the use of multiple spi devices. It explained about the use of pull up resistors on the enable pin of every device you have on this bus for this specific problem. Just to be sure when I was testing it I did not connect the nrf24. I added that resistor to this PCB. So far it's works with the MySbootloader and just burning the program with the USBASP. Even with the nrf connected. I really believe that it was the chip itself. But I still have them waiting for a better test environment.

@Joerideman said in home Assistant and OTA support and node to node: @MatiasV BTW why did you switch to mqtt? The wifi GW accepts multiple connections. I was experiencing problems when starting the HA "server" (AKA Old laptop) and GW, or while the WIFI was temporary off for any cause. We had some rough weeks with our electricity company. The GW would disconnect from HA and I had to restart the GW or sometimes even HA to get it working again. It was a mayor headache while I was out of the house, the MQTT GW is way more reliable for me.

Thanks, I guess what i am trying to find out is how i get my sensors code to use the Adafruit_PWMServoDriver code to do the same as you than. I would like to control 5 sets of RGB strips by 5 separate V_RGB faders in domoticz using my sensors. But i cant figure out how to get mysensors to tell the PCA9685 chip how to controll the channels.

I have to admit TheoL I've spend some time looking and admiring your work. But I have not found your examples. I will look into the OTA programming, sounds great. My holiday is over, and the next one starts in july. This topic will probably sink down during this period ;-).
