We have 2 plastic covered hoophouses & a frame covered with fiberglass sheets. All have furnaces on thermostates, plenty of fans also on thermostates. Some of these are self opening shutters.
We never leave our greenhouses when things are growing!

A cloudy day can cause furance to run, then sun pops out & it will soon be cooking plants. If sun is out & it turns cloudy. you may be blowing your furance heat out the vents.
Also plants can not go more than 1 day without watering.
Things dry out very fast in greenhouse.

If you install everything to run automatically, it will be very EXPENSIVE! I would still not trust it!
Just to much value to leave it in care of a mechanical contraption.

P.S. our end walls are all built just like a regular wall; 2 X 4's with fiberglass insulation, sheeted with plywood.
You don't need the light from the endwall as much as the insulation factor.
