I have an electric water heater. It has a top and bottom thermostat. In the summer I turn these down and in the winter turn them up. It's a real hassle because I have to unscrew the plates and then adjust the thermostat. If I get it wrong I have to do it again and would like to do micro-adjustments until I get it right. There are 2 modifications that I want to consider for this tank and need your input for.
Is it possible to attach a knob on the outside of the tank that could control this thermostat without me having to unscrew that plate each time?
Is there a way to control this wirelessly? I would absolutely consider a Raspberry Pi or equivalent project to get this working.
The purpose of this question is to find a way to easily way to adjust the two thermostats on the tank so the answers aren't limited to 1 and 2 above.
