HI guys, im off grid, during winter my underfloor heating with is in 5 zones and each zone is controller by a smart curcuit breaker (ewelink). Now when we go to use our cooker id like the 5 underfloor heating zones to turn off, when the the cooking is finished the undefloor heating turns back on.
Ive looked at a current sensing device inline with the cooker feed curcuit that could trigger a contact which could be used in a scenet to turn off the 5 x smart switches.
The smart curcuit breaker have the capability to send an alarm to the phone, could this message be used to trigger the 5 x smart heat curcuit switches?
Im open to suggestions from anyone.
The idea is to reduce the load on the inverters so either underfloor heating or cooker…not both at the same time
Maybe try plugging the cooker into one of those current-metering sockets. https://sonoff.tech/collections/smart-plugs
They have an option to create a scene when the load exceeds a certain level, and then the scene will turn off the heating. And vice versa.
My Sonoff S60 has this option.
The problem might be synchronizing this to make sense. You’d have to determine the minimum current draw the cooker draws when it’s on but not doing anything. Then add a delay before it shuts off due to low consumption.
Or you can do it manually using a button.
In general, modern appliances draw very little power when they’re only on standby, which Sonoff handles very poorly or doesn’t handle at all.
So, if the cooker is on but in standby mode, it draws so little that you don’t mind it being on along with the heating. However, when the cooker starts with a power consumption above the set level, a scene will trigger that turns off the heating. When power consumption drops, turn on the heating and the cooker will go to standby. Unless you don’t want standby, then it’s even simpler.
Of course, it’s not perfect, because depending on the response time and execution of the scene, the inverter will be under load, but we’re talking about milliseconds or a second or two.
