@electrik I think about it but when I open the sensor and press reset to test - sensor is dead. No power indicators, no blinking. Also my sketch presents sensor at every boot. In HA logs it will be written lines like "node 9 cannot add child 1 already existing" etc. but log is empty.

Also without resetting another battery sensor I cannot bring to life my network. It should be some kind of simple mistake but I cannot find it Node id are different and sensor data when battery is charged are correct.

Maybe sensor send some kind of incomplete or spam messages? All other sensors become inactive from HA perspective - it looks like some gateway problem... or HA. I'm really confused. I can try to power off arduino when battery is almost empty but dont like this kind of solutions

Hi,

I have strange problem with my battery powered BME280 sensors. I use Easy/Newbie PCB for all my sensors (wall and battery powered). Hardware works fine I think because all my wall powered sensors works ok almost one year now.

Battery sensors works ok when I disconnect it from battery and charge before power loss. Every time when I let it power off itself my gateway hangs and all sensors data didn't show in Home Assistant. Also debug logs in HA didn't show any communication from gateway. I have 2 the same battery sensors powered by two 18650 cells (sketch is the same, difference is another node id). When this situation happens I have to restart all my network to get it working again. I have all my wall powered sensors on one circuit so I can easily reboot them. But without restarting battery sensor (this one still powered) network doesn't work.

I cannot do debug of powered off sensor. Debug logs in Home Assistant shows nothing (no log from gateway). I cannot reconnect serial console to gateway because it will reboot the gateway...

I upgraded my gateway and battery powered sensors to newest mysensors version, but I use old RMF69 driver - I don't know it it relevant or not.

Gateway sketch is the standard one - radio type, channels, encryption only

battery sensor and gateway sketch is below

Any ideas what is wrong?

V_VARx not working because HA saves states/data from mysensors to file. When you update sensor data from HA that file doesn't change.

I can send data to node by V_TEXT messages using notify service. It works

I need set some parameters in Home Assistant and send it to mysensors node. I far I know I can do it by S_CUSTOM sensor type and V_VARx values.

But how to set it in Home Assistant? I want to have input text/number field in Home Assistant to store parameters.

For example:

I've temperature sensor and want to switch relay (starts fan) when temperature reach parameter set in Home Assistant input number field.

Hi, I've lipo battery pack with 4,2v maximum voltage (3,6v nominal). Can I safely use it with this board? Do I need any modifications?
