Ventilation automation with bypass

Configuration
1

Hi

i am trying to make a ventilation automation based on VOC and Humidity with a bypass button.

i almost got it working :slight_smile:

1 fan on the roof.
I got 3 humidity sensors that starts the fan if one of them goes over 70% and turns off the fan again is all are under 50%

I got 2 VOC sensors that turn on the fan if the value is over 200 and off again if both are under 100. all 5 sensors in same automation :slight_smile:

i only have problems getting my sonoff button SNZB-01 to act as a bypass button for when i want to start a fire in the fireplace.
reason for bypass that i get a backdraft through the chimney and fills the whole house with smoke if the fan is running.

promlem is that SNZB-01 it is not a sensor and it only triggers an event and i cant seem to get it right :frowning:

any ideas where i f… up ?
