Many times during hot periods lots of people use water for domestic usage including garden irigation. As consequence I often get no water for my house. Having a fountain in my yard I decided to make automation of the water supply using electro valves as actuators and sonoff for wireless commands. Below the schematics for hydraulic connections.
The instalation was done in a small room, below ground level, concentrating the comand panel, irrigation valves and all pipes for the consumers. The well is closed to this chamber and typically has 3 cubic of water offering enough buffer for irrigation and domestic supply.
The operating modes for the instalation are listed described below with assosciated valve and pump manipulation.
For command part I used 2 Sonoff 4CH Pro ( 8 channels in total for electrovalves), 1 Sonoff TH16 for humidity, temperature and light control, 3 Sonoff basic (2 for pumps) and one for shuting down the control panel.
My project was focusing more on automation but the coats went high. My neiboor used a simpler approach with one electrovalve (R2 from the picture below) and thinks look good in the end. Recomended for cost to function approach.
