quatt app on homey pro, sorry, I meant update 12.10.0
Hi, succeeded! It seems it takes a while to connect with the cic! kind regards, Jos
Iâve Quatt version 1.8.0 installed. I cannot get remote control working.
After I followed the steps âProbeer te reparerenâ and following the steps the pairing process doesnât work. It returns an âinvalid_setting_typeâ.
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 havenât 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.
@Denn1s any tips here?
Ill take a look asap 
got a few things cooking anyway, including bug fixes.
Isnât this the moment where the heatpump is defrosting? At least, thatâs how I check how often the heatpump defrosts. So the heatpump is taking thermal energy rather than providing. I guess thatâs the rationale of the negative sign
Hi, good to hear! I havenât seen negative values before for thermal power before. Itâs just one of the other values that are copied as is. Could be what Jean Pierre saysâŠ
Hereâs an example of defrost moments last night. As you can see, there are short ânegativeâ thermal power spikes. Is this the kind of negative values you are referring to?
Donât 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.
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 ?
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 Iâd suggest you have a look once a while. At a certain moment youâll 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 doesnât 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/PinâŠ
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.
Just received the new update, thanks! I did notice however that my system now continuously indicates that the CV is on⊠do others notice that as wel?
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 âCV should heatâ and âCV heatingâ.
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!
Is it possible to add a trigger for the defrost? To start an Action when defrost is activated?
I think youâre looking for the trigger supervisory control mode. There are some antifreeze modes there you can trigger on.
I Will have a look then, I couldnât find them this morning.but maybe I overlooked it
