[APP][Pro] myVaillant - Comfort for your home

[R5Turbo]

@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

  "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 …

    "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.

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…

I seem to have the same issue.
