How to check if a device is disconnected / not available? (lua, HC3)

[HarmLammers 2]

I have an Aeotec Multisensor 6 which is temporarily not connected. If I read out the temperature using fibaro.getValue I get the last value measured when the sensor was still connected, which is of course not the current temperature. I’m reading a bunch of sensors to get the maximum temperature, so I’d like to ignore sensors which are disconnected / not available. How do I test if a sensor is available?

I wrote a little function to check if a sensor is dead or inactive for too long:

no how.

dead devices - devices what do not respond on some action within some period.

just disconnected devices never detected as dead. only after some period HC3 can mark this device as dead.

 

if you asking how to detect?

ok this is example (not full code for use)

Thanks @10der!

 

In the meanwhile I found a different solution: using fibaro.get instead of fibaro.getValue and check how old the data is. Since I’m measuring temperature and humidity in a place where a lot of fluctuation is to be expected (a corridor/staircase with glass roof, a kitchen and two bathrooms), I just ignore data older than 3 hours:
