@llasking Have a look on the arduino forum or github - I still use the older tmrh library for point-to-point on things made before I changed over to mysensors. There is also a nrf24-lite library as well, but I have never used it.
@Mati_Smart, if the messages from the sensor are arriving in domoticz, it must be some configuration in domoticz itself.
Can't help you here, I don't know domoticz.
Did you search already on the domoticz forum?
@btmerz Your welcome
Just for clarification, is it working with standard Mysensors library, or the one I've pointed to?
I still have some spare LGT8F328P boards, so if the standard library is working with tis board definition, it will help mee too.
