I am trying to setup Home Assistant with MySensors. Current setup is Rpi 3 , W5100 Ethernet gateway with NRF24 radios. All communication seems fine but the sensor wont register. HA log shows Node ID 10 is unknown. Node ID 10 is a MySensors 2 Motion Sensor.
Here is my Gateway log
Here is my Sensor Log
How do I tell HA what node 10 is? The auto detection does not seem to be working for the Sensor. It does find my Roku device but that is all.
Motion Sensor Sketch
Logs and sketch look fine. What does a debug level log from HA look like?
Hi Martin,
Thanks for your reply. I found a post from you that had some sample code in it about a gateway issue and I noticed I the mysensors platform id grouped with the default weather sensor instead of with the mysensors gateway section. Once I move that it identified the node correctly.
Can this code be shared? Decided today to switch from pure MQTT (not mysensors mqtt) gateway setup to mysensors gateway (connected like ethernet gateway). But having some problems… Instead of two switches get only one
Got the following. But as can be seen from below code - have two of them
switch.vent_klapans_56_7 on device: 127.0.0.1

Your sketch doesn’t seem to send any values for the two relays. Each device needs to send at least one initial value to be added to home assistant.
PS: your sketch contains six children in total. 1 temp, 1 humidity, 2 buttons (1 S_DOOR, 1 S_LIGHT) and 2 relays (2 S_LIGHT). The switch you showed attributes for is the second button child.
Ok got that for relays. But what about the sensors? Considering they are constantly updating their status - shouldn’e i see them after an update?
I would need to see debug logs from home assistant and your arduino, to try to answer that.
