we replaced our old oil burner with a new air heat pump and I`ve chosen a product that had some kind of smart home integration. I just had to add the great KM200 Binding from @Markinus to manage the heat pump via OH. the first thing I optimized was the time when the heat pump heats the warm water t…

[image] powerpolly: anybody else optimizing a heat-pump with OH? Yes, I’m even selling an energy management system that does this based on OH (sorry for the advertising break). It’s got a slightly different approach on run times as it is primarily targeting PV power cost savings. When you h…

My first heat pump died after 8 years and my new one has a Tuya controller built in. I find they (heat pumps) work well, just you have to run to them when the air is hottest and hopefully your solar is producing for best savings. I have a sensor glued to the shower pipe that knows when the first sh…

[image] mstormi: I’d be interested to know how do you determine how long to (pre-)heat. not sure if I got your question, I don’t care about the heat time. the boiler stops when the setpoint temp is reached. buderus allows to define a chargeduration after which the boiler also stops. [imag…

[image] powerpolly: not sure if I got your question, I don’t care about the heat time. the boiler stops when the setpoint temp is reached. buderus allows to define a chargeduration after which the boiler also stops. Explicit charge duration or setpoint to stop heating is different ways to ult…

[image] mstormi: So how do you determine the heating stop setpoint ? I have three heating circuits, one for floor heating, one for radiators and one for the external hot-water tank. till now I only tuned the hot-water heating process: heat up once a day when max outside temp is reached. the …

I meanwhile have extended our energy management system so it now can combine cheapest hours of a dynamic tariff with PV surplus into an ‘energy availability index’ that’s used to run/charge all sorts of time-variable consumption such as delayed start of washing machine, EV charging and of course hea…

I am looking to optimize my warm water circulation system. My current setup includes an extra pipe to each warm water endpoint, with a circulation pump that distributes warm water three times per hour. Here’s how I plan to optimize it: Stop the Circulation Pump When Nobody is Home: I have a wor…

I do operate my cirulation pump with a sonoff device, a motion sensor in the bathroom starts the pump only when movement occures during times we usually have a shower. having a shower outside of these hours I can manually start the pump with a voice command to Alexa. the runtime of the pump is only …

My last option is something similar. I am also thinking of going with EMS Gateway from BBGKees. On their wiki, I found some references to the circulation pump, which on the KM200 things channels do not see: [image]
