Old pool with 3-fase cirkulation pump and 1-fase heat pump (without wifi). Wish to control both and through wifi/lan. Need to stop the cirkulation pump every 12 hours and depending on water temp shut down the heat pump now and then. Shelly Pro 4PM and Shelly Pro 1PM seems to met my wishes incl. power consuming, acc. power and shedule everything.
Will history and set time be kept when power is cut off?
Can I use Shelly DS18B20 Temp. sensor in the same Shelly Pro 1PM as the heat pump?
Has Shelly another unit for 3-fase with wifi and history?
