How to detect if the node became unresponsive?

[rzylius]

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

@rzylius I don't know if your controller supports it but you can check out heartbeat function in MySensors and how that works.

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

@rzylius - there are many ways probably, so its fine as a general one. I would also google arduino watchdog which can be a good tool if you suspect your node will go unresponsive.

I did some looking on this a while back and found this external solution https://github.com/mattbornski/Arduino-Watchdog-Circuit . It is a hardware watchdog timer based on a 555 timer IC.
