@Pallieter thank you for the bugfixes. I think it could make sense to display as well the “heatingCurve” . In my example below it’s the value ‘0.35’. Btw. thanks a lot for the app. good job! [https://api.vaillant-group.com/service-connected-control/end-user-app-api/v1/systems/{systemId}/tli](https://api.vaillant-group.com/service-connected-control/end-user-app-api/v1/systems/%7BsystemId%7D/tli) ```json "circuits": [ { "index": 0, "heatingCurve": 0.35, "heatingFlowTemperatureMinimumSetpoint": 20.0, "heatingFlowTemperatureMaximumSetpoint": 90.0, "heatDemandLimitedByOutsideTemperature": 16.0, "heatingCircuitFlowSetpointExcessOffset": 0.0, "epsilon": 2.0, "setbackModeEnabled": true, "roomTemperatureControlMode": "NON" } ], ``` What is missing as well is the control for HotWater. At the moment my system is on “AUTO” mode. However sometimes during vacation I disable hot water to save money. So it would be great if we could see the mode and change it. If you wanna escalate you could display timeProgram for hotWater as well 😂 , but that will be a bit more work and not that important … ```json "domesticHotWater": [ { "index": 255, "operationModeDomesticHotWater": "AUTO", "tappingSetpoint": 57.0, "holidayStartDateTime": "2014-12-31T23:00:00Z", "holidayEndDateTime": "2014-12-31T23:00:00Z", "timeProgramDomesticHotWater": { "metaInfo": { "minSlotsPerDay": 0, "maxSlotsPerDay": 3, "setpointRequiredPerSlot": false }, "monday": [ { "startTime": 360, "endTime": 1350 } ], "tuesday": [ { "startTime": 360, "endTime": 1350 } ], ``` ---

I quickly checked the github code. At the moment I think the app works only with vaillant (login part seems to be hardcoded to vaillant). Sorry. ---

hello, I set my VRC700 to vacationmode when i leave the house for a few hours. i would like to activate some flows when vacationmode is activated on my vrc700, but i can’t find any card that would be suitable for this. ---

> [@Pallieter](#): > > @sschot No, pushing outside temperature data won’t be possible. But it is maybe possible to simulate the working of a heat-curve. By setting the heating circuit temperature based on a from internet retrieved outside temperature. Will take a look if I can add an action card for setting the heating circuit temperature. Is there any progress on this matter? Looking forward to your news with interest! ---

I can think of a few possible applications. Initially, I only wanted to monitor the flow temperature in my new heating system. Now, however, I would like to control my fan coil unit depending on the flow temperature – the fan should only run when a minimum flow temperature is reached. I also have other temperature-dependent control options in mind. ---

Congrats on releasing V2. I was thinking how helpful it would be to see the current flow temp in Homey. Same day, my app was updated. Unfortunately the app doesn’t read any data, nothing is being read from the VR921 device. I tried repairing. This takes me to a login page. If I enter wrong credentials I get feedback that authentication failed with a chance to re-enter credentials and submit the form again. If I enter what I believe to be the correct credentials, I am given the same feedback AND the Homey app navigates back from the WebView with your form and back to the native Homey app. Hope to use this app again soon. ![1000047191](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/0/e0c161dfa80f8c354ade2cb833d4f8a1422e9020.jpeg) ---

Since latest 2.0.0 update of myVaillant app, i cant see any sensor anymore, only the status and energy are read from my Arotherm plus vwl 55/6 I have tried several homey restarts, repair app, delete device and re-add, restart Vaillant gateway etc… In previous app version everything was fine and besides app update nothing has changed. Any tips or just have to wait for new app version? Several Vaillant flows are broken now… ![capture_temp](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/b/5/b5057936379e06be2964c6f314515f392d9a7f63.jpeg) ---

@Pallieter Is it possible to assist you with the translation into German? I just need the correct format or a table in which I can enter the German translation. ---

Hi - maybe related to version 2.0.0 and similar issues noted above. I am getting the following error when adding new devices: `Cannot read properties of undefined (reading map')` ![Screenshot 2026-02-04 at 14.52.24](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/f/8/f8bcc56997c5f4ffa75426e0a8db89c020aa0952.png) Eventually the devices are discovered and I can add. However I get the following issues: I have flows to automate to set a zone temperature. However the cards are triggering the wrong Zone. I.e. Set Temperature for Zone 1 is actually sets for Zone 2 - this only occurs when using cards, not the actually device in the homey zone. When I go to the device in the Zone and up the temperature the right zone is updated. My Vaillant equipment: Gateway: VR 940f (404.1.28) 3 x VRC sensoCOMFORT [720] ---

I am finding the status flow card is not responding as intended anymore. I can select “Verwarming” or “Warm water” when I use this flow card, but the actual status value is “HEATING” and “DHW” –\> I checked this by sending status value to my phone. Did Vaillant change something? So the flow card is not firing. I changed language setting to English but there also the shortlist of values in the dropdown box do not match the actual status values. EDIT: it is responding to “Verwarming” or as shown “HEATING”. Yesterday it was not responding to “DHW” or “Warm water”. @Pallieter is this something you can check and fix? Other people with similaro experience here? ---

Hello, noticed something strange with my heating and i think it might have to do something with the homey-app. i set my VRC700 to vacationmode on may 16th (like i always do). at the end of may i noticed that my radioators were heating, i checked my VRC700 and it was still in vacationmode, so my desired temperature should have been 15°C. i checked in the homey-app and saw it was at 23°C (which is higher then we put it normally) i even saw it go to 23.9 and 24.1 at some points in my insights. so apparently on may 21 at 8 o’clock my vacationmode was canceled and i never noticed since the screen on my vrc700 keeps saying vacation activated. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/8/e/8eafb7ea8aacbc79baf24ba2548190ab2359af70.png) so when i found out i deactivated and reactivated vacationmode on my vrc700 and it was fine again, but today i noticed my radiators were warm again, so i checked my insights and it happened again. ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/1/8/1800de9fa16348eca626dfe03a8baa2c851f2072.png) are there more people who have this problem? or did someone already found a solution? Edit: i reactivated vacationmode but put it on 10 degrees this time. here are my insights from the last 3 days. I see that the 10 degrees are only briefly activated, and yet ibdontbhave any flows to put the weird values the thermostat gets. ![IMG_0737](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/a/b/abc19f19d08cadc70781dff781ca23ce77dd9868.png) ![IMG_0738](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/f/df8ca91c1ebd054fa97f254f282ffa9d2bbe6e56.png) ---

Hi, since yesterday all my values are not updating anymore. Tried a repair and values come once, waited for an hour, no update. On the android app I do get updates constantly. After a restart of the app no values appear anymore. After setting the app to not active and back to active no values appear. Only after another repair I get up to date values once.

Same with me. Reset the heatpump, restart Homey, restart the app. The Zone (gateway/thermostate) does give data. The Vaillant Android app is working fine. Something is suddenly blocking the heatpump data to Homey. ---

Same here. I’m wondering if Vaillaint isn´t blocking our api calls from Homey since their infrastructure will probably suffer heavy demands from android apps with the heat waves in Europe. Glad to see i’m not the only one though. ---
