<![CDATA[How to detect if the node became unresponsive?]]>Hi,

I developed mysensors actuator for controlling ventilation device (power on/off and speed). I use openhab as controller.

I would like to be sure that I notice if mysensors actuator become unresponsive. please suggest how controller should recognize if actuator is unresponsive.

regards,

Rimantas

It is a hardware watchdog timer based on a 555 timer IC.

I would also google arduino watchdog which can be a good tool if you suspect your node will go unresponsive.

Thanks, I guess then it is more OpenHab group question, than general one?
