Hi, succeeded! It seems it takes a while to connect with the cic! kind regards, Jos ---

I’ve Quatt version 1.8.0 installed. I cannot get remote control working. After I followed the steps ‘Probeer te repareren’ and following the steps the pairing process doesn’t work. It returns an ‘invalid\_setting\_type’. I assume I can enter any First and Last name? Any clues how to get this working? ---

@trietsch many thanks for this Quatt app. I am enjoying a detailed view of my Quatt in HDashboards. One surprising observation, occasionally a small series of negative Thermal Power data points is recorded. Obviously no such thing as my Quatt is only heating. I haven’t found any malfunction in the operation of my Quatt. May i ask for a data integrity check to be added and to record such incoming negative values as zero. Happy to further investigate based on your detailed instructions. ---

Isn’t this the moment where the heatpump is defrosting? At least, that’s how I check how often the heatpump defrosts. So the heatpump is taking thermal energy rather than providing. I guess that’s the rationale of the negative sign ---

Hi, good to hear! I haven’t seen negative values before for thermal power before. It’s just one of the other values that are copied as is. Could be what Jean Pierre says… ---

Here’s an example of defrost moments last night. As you can see, there are short ‘negative’ thermal power spikes. Is this the kind of negative values you are referring to? ![Screenshot_20251224_091750_Homey](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/9/f9dbae36a9e3405172bbdc07be5677ed27b4b84f.jpeg) ---

Don’t think so. I see negative Thermal power spikes while heatpump is operational. I.e. water temperature is well above freezing and flowing (!) What i do see is +40W Power Usage while heatpump is in Standby (no warm water flowing). I believe that to be a small electric heating to prevent freezing. ![Quatt 2025-12-24 at 19.54.39](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/5/a58409748de416f23af63b4dc8682eaede741290.png) Maybe this is a question for Quatt. Looks like some operational transition (Power Usage rises, then drops and then return to original level) result in a negative Thermal power. A simple miscalculation ? Do others see these patterns ? ![Quatt 6hrs 2025-12-24 at 20.14.11](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/3/9/39a8d2ade264ca2a0ba4d4047d4181763e6db023.png) ---

This looks like regular defrostcycles to me. Water temperature and flow will remain at normal levels during these cycles. The heatpump will reverse the flow in these cycles and use the warm water to defrost the backside of the pump. Currently, there will be almost no frost at the backside of the unit due to the low humidity but I’d suggest you have a look once a while. At a certain moment you’ll see quite some ice that prevents the airflow. The defrostcycles remove the ice. ---

Great app and the widget is a great addition. I see that the widget for Quatt duo doesn’t calculate a correct COP if only one HP is running. It seems to average the COPs of both, but as one is off it just shows half the value it should. The calculation should be simple, though, Pout/Pin… ![IMG_1478](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/4/d43dbb8a9d06e8adab833ada2af779b56201f04a.jpeg) ---

This was indeed already reported above, and I already implemented a fix but no release just yet. Doing a few other bug fixes this week. ---

No, nothing changed on that part either. Or at least, no code logic has been changed on that end. Only widgets updates were pushed. ---

No issues here @Patrick_Van_Deursen . Which capability are you looking at? There are multiple, such as “CV should heat” and “CV heating”. ---

apparently something else changed on my side. system was asking for gas for a very long time, leading to my confusion. Solved for now here. thanks! ---

I think you’re looking for the trigger supervisory control mode. There are some antifreeze modes there you can trigger on. ---
