I used to use sun.sun to control my lights outside. I figured it out that basically I can use generic thermostat to do the same job with my illuminance-sensor. The only problem is that generic thermostat use only celsius (fahrenheit) as unit of measurement instead of lux. It is not a big deal but I would prefer lx instead in this purpose.
Is there any way to edit that - could generic thermostat be modified for this purpose? Or is there already a easy as this tool for the job?
