I don't have a web site, and don't know how to set one up. it's not even a low priority at this time. I am still trying to document the system so if I am unavailable (70 years now), someone will be able to keep the system reliable. The way things are going, I expect we will have rolling blackouts that I may possibly see. I have had conversation with our power supply, a rural electric coop, instead of just controlling my air conditioning when peak shaving is needed, my generator will come on, automatically transfer us off the grid.
