Same here. Was promised nothing would break when I handed over the app but everything broke for as well. Well lesson learned.
Also shows wrong data on inlet and outlet for me compared to the unit and aqua temp app 0.5 degrees wrong.
Just give the feedback to Jesper. I’m sure he’ll look at it and fix it.
I’m glad development is back on track now!
Please can you send a diagnose report. But it sounds like you mey be on some kind of different backend system than what I see and have access to. So it may seem that some heatpumps actually works using the old backend, and some only works on the new.
Since homey will not allow two different apps for the same product, we need to merge the 2 different solutions together then.
Does the newest version of the official aqautemp app actually work with your heatpump?
The thing about being logged out is not something I can do anything about. That is just how the backend system is done. You can read the same issues for users on aqautemp app for home assistent.
I have done nothing in the app that changes the inlet and outlet temperature from what is received from the backend systems.
Reading your post again, I read it as it actually works now, but you needed to reinstall the device, and this was a pain since this means you needed to update existing flows, or?
Well I am sorry for that. Lessons learned.
Thanks for your work @Jesper_Rasmussen! needed to reinstall the device to but the login procedure is now easier. You can’t make an omelet without breaking some eggs ![]()
Not a big pain :-), just some one-time work to transfer the flows to the new device. More unfortunate that you’re logged out of the Aqua Temp app.
Thanks for maintaining this app, it’s appreciated.
Hi, I am still on the Beta but have seen for quite a few weeks random actions on my pump from Aquatemp. I use a flow to control my pump and deleted the phone app a long time ago. Can you please help why these yellow highlighted actions are happening? I tested, the manual action looks different (last one on the list). Thnak you!
I see similar behaviour. Not sure what’s triggering it.
I’m experimenting a bit with flows to see how/when it’s triggered.
Side question, you can switch of the heatpump by either setting the mode to OFF, or by turning it OFF. Both can be done from the device or in flows.
Is there a difference between both?
Thanks, would be interesting to understand the trigger/reason for these. Not sure if there is some tracing possibility?
I will check to see if I see the same behaviour on my heatpump.
Does this turning back on happens right after the flow has turned it off? If that is the case then it is probably not turning off at all, and just gets updated back to the old value again on the following update from heatpump.
I am a little confused about this as well, but I will try some experiments in the following days.
I also see that when turning it off in the homey app, the target temperature changes to something diffent. If I turn it back on again it switches back to old target temperature.
Thanks a lot for looking into this! It is random, doesn’t always happen when I turn on/off via a flow. It is rare but it also changes temperature sometimea (did yesterday for me also when it turned off, one degree down) - this change is not showing up in the log but I have a notification set for all temp changes so I saw it yesterday.
Thanks again!
So I see that it works like this:
There are 4 modes
- Cooling
- Heating
- Automatic
- Off (not really a mode, only exists in homey app because it is a standard from homey, as this used as a thermostat capability)
Each mode has its own target temperature, so when the mode changes the target temperature may change to. This is same behavior as when using the official app. So you would have to be in the right mode when setting/changing the target temperature.
But then there comes something a little tricky. If you turn the device off, the homey app will then show target temperature for cooling. So if the device is off and you change the target temperature then you will only change the target temperature for the cooling mode.
Also only in the homey app, if you choose Off under modes, it will turn off and switch to cooling mode.
But this does not explain to me why the device turns on by itself. Punkportaldan, what flowcard do you use for turning on and off? The mode switch or simple on/off?
Interesting results, thanks a lot! I am always in Heating and Off modes. I need to doublecheck not to change temperatures when being in Off mode, I don’t think I do that but I might need a delay to avoid turning on and changing temperature at the same time.
I am using Turn on and off cards that look like this:
I have been wondering about this double OFF feature.
To avoid confusion I think that there should only be only way to turn the unit on or off.
So either it is a mode, or it is a switch.
Since the Aquatemp system don’t have an OFF mode, but this is some artificial homey stuff, I am thinking about removing that mode, so that it will match the modes on the official AqauTemp app. (auto/heating/cooling)
What do you guys think about that?
New version 1.8.0 out for test
A new version has just been released for test. It adds:
- Temperature for evaporator coil
- Temperature for exhaust
- Fan speed
And this version also adds better error handling, so I do not get an email every time the homey cannot connect to server due to bad internet and other stuff.
If the connection to server goes down, a marker will be added to the device icon in the homey app, and if user clicks on it, it will tell what is wrong. If the user really think that something is wrong, then the user can manually create and send a diagnosis report.
By the way, I have found the modbus specification for the aqautemp unit. So now I can easily get every setting or value from the heatpump. So if anyone is missing something, it might be available.
I am thinking of added defrosting as a status.
Hi Jesper,
in the past i controller the heatpump using Home Assistant, controller from Homey. The ON/OFF was a switch (like on every device like a lamp). The mode was only for setting it to auto/cool/heat. That made most sense to me.
With regards to reading out stuff, have you find other options to control the heatpump? The only way i found was by setting the temperature (= setting it to 35 degrees immediately forces the heatpump to blast to 100%), or by setting the silent mode to on (sets it to 54%). That works to control, but if there are more granular controls to set the compressor frequency, we might match it even to more to the solar output of PV panels.
Thanks for the efforts!
