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.
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?
