Turn off switch if sensor can't collect data

[BashSer]

~22:30-01:30 one sensor disconnected from vcc and environment schedule(heater) continue work and for 3 hours temp up on 10C degrees. If i did not check this before going sleep this can fired...
Can you add check in cycle update ?
If int(last temp/hum data = none) > 20 then Turn off environment and turn off switches else pass
This can save from flood or fire

Hi,

I understand your issue. I need to think about this. There are multiple solutions... so let me think about this for a few days

Nice, thank you !

Done, first attempt.

When a sensor is disconnected for more then 10 minutes, it will show an error badge / sign on the dashboard page, and sensor page.

The power will be forced to be off when there are zero sensors working

On work i start rpi2(no any connected sensors) - yes, error sign shows on dashboard page and off switch.

Test scenario:
Connect temperature sensor and switch. Configure environment.
Heat temperature sensor for evironment switch on. After this disconnect temperature sensor and wait.
After time switch in evironment off and on dashbooard page shows error sign. In log and "screen -r" write about this.
After connect temperature sensor and wait. Environment works and switch on again.

Looks all works fine =)

Ok, then I close this issue.
