Hi,
I have recently installed a Shelly 1PM to control my water heater. It works well. I program it to run 2h between 01.00 and 03.00 when the electricity price is usually very low. I have the electricity with hourly price. It is sometimes a better price at different hours. The price is known around 13:00 for the day after. So the price is known and it is possible to select the cheapest hours. It is awkward to do this everyday and therefore I would like to make the selection automatic.
Can the cost of electricity be read in to Shelly? I think it could be like a synthetic sensor where you say what electricity price area you are in and the price is available in the Shelly APP. The price is available from any of the electricity market operators like Nordpool and EPEX. Probably other places as well more convenient for fetching.
For the water heater 2h starting 01.00 is OK. But for all my electricity heated floors I would like to go full speed when the price is below 0.05 EURO and at least the 4h with lowest price.
Is there any way for me to achieve this in Shelly?
Kind regards,
Linus
