Heat Pump Ariston #1

Hi, I am very happy with your project. I integrated it perfectly into Home Assistant. It would be nice, however, to have the opportunity to understand if the heat pump is heating or hot water

Glad to hear you have it working. Is not possible to distinguish the working Mode, as the API is only sending ON ir OFF. A pity because I looked for It a lot. To have a past measure of that, I've created a secondary measure in home assistant graffana, that checks when the heat pump is on and the derivate of the water temperature curve is positive, a little complex, but working.

hello, I installed a few sensors and I managed to achieve this result, it remains only to distinguish qunado is doing heating or DHW. I think I will use the state of the 3 way valve to derive the state.

Wow, amazing data, and sensors.

How do you plan to get the state of the 3 way valve?

And how do you get the flux (flusso) data?

I'm planning to add the consumption data that provides the web to this integration, but I guess it will be very unreal. I only have a general consumption sensor ( main input of the house ) and it shows bigger vaules than the Ariston data, like 5 to 10 times bigger, when only the heat pump is in use.

My 3-way valve has COM, NC, NO outputs as a relay.

The pump consumption is read through an sdm230 connected to a sonoff with tasmota. At the moment the flow meter does not work well because it needs a 5v power supply. To calculate the COP I always set the pump to maximum (17 l/min).

The values ​​indicated by the pump do not take into consideration the circulator (about 52Wh) which in 24h of use correspond to 1.24 kWh
