Failed to create HeaterCooler accessory from device

[v1fckoeln]

Describe The Bug: Failed to create HeaterCooler accessory from device ( Daikin ALTHERMA Heatpump with hot water tank) WHILE 3 additional Daikin air conditioning units are added well. To Reproduce:

Restarting the daikon cloud plugin

Expected behavior:

Showing the indoor, outdoor and hot-water tank-temperature Logs:

Thanks, this if useful. I only have 2 specific Daikin AC’s so hard to make other devices work without actual device information.

I am now on holiday. If all goes well I will be able to fix this when I am back the last week of August.

[jwillemsen]

@JeroenVdb Maybe helpful, as part of the daikin_onecta HA integration I have several fixtures with daikin device data in various states, see https://github.com/jwillemsen/daikin_onecta/tree/master/tests/fixtures

[JeroenVdb]

@v1fckoeln is I understand correctly you can not set up a room temperature but only a "leavingWaterOffset". Is that correct?

[JeroenVdb]

I released homebridge-daikin-cloud@2.6.0-beta.4 that should fix the error @v1fckoeln.

Could you help me understand how your device works? Can you set the roomTemperature, from the device data I see you can't but maybe you can if you change some setting? Nonetheless the plugin now adds and removes the characteristic if it seems it can set room temperature.

[v1fckoeln]

@v1fckoeln is I understand correctly you can not set up a room temperature but only a "leavingWaterOffset". Is that correct?

Yes that's right. The Onecta app outputs the Altherma heater as the climate control. An offset of -10 to +10 degrees flow temperature can be set. Onecta outputs the specified indoor temperature, the outdoor temperature and flow temperature as sensors.

You can set from 0 to -10 or +10 as offset. FYI: I installed the new beta :-) And it makes me happy. Thank's a lot. Hot Water Tank is available now in home bridge and shown as Altherma (nicer 'Hot Water Tank)' in the Home-App - but it's OK for me. :You have to click on 'Show as separate tiles' in the Home app. Then the heater and hot-water container are shown separately. What you can maybe add additionally is (proposal) the outdoor-temperature as 'Alth.-outdoor temp', indoor-temperature as 'Alth.-Indoor-SetPoint' and the flow temperature as 'Alth.-flow temp' But anyway: Thank you very much for the quick implementation.

[JeroenVdb]

I don't totally understand what you said. Am I correct that

Hot Water Tank is available now in home bridge and shown as Altherma (nicer 'Hot Water Tank)' in the Home-App - but it's OK for me. :You have to click on 'Show as separate tiles' in the Home app. Then the heater and hot-water container are shown separately.

So the device shows up correctly in the app: 1 device with 2 "tiles" (services in HomeKit terms) but both tiles are named "Altherma" and it would be more logical if secondary service, the hot water tank, is called "Hot water tank".

You are totally right of course, I fixed it in a new beta version: homebridge-daikin-cloud@2.6.0-beta.5.

What you can maybe add additionally is (proposal) the outdoor-temperature as 'Alth.-outdoor temp', indoor-temperature as 'Alth.-Indoor-SetPoint' and the flow temperature as 'Alth.-flow temp'

What do you mean with this exactly? Do you mean sensors or the possibility to set a specific setting? If you feel comfortable with some JSON data, maybe you could point out what setting you want to expose (sensor) or change.

In the Onecta-App are shown the values from the sensors told above -sensor only. Where can I find the json data with possible datapoints?
