[beanian]

Home Assistant release (hass --version):
0.53.1

Component/platform:
Tado

Description of problem:
Error creating the climate components when Hot Water is part of your tado system

Expected:
climate components get created for each zone

Traceback (if applicable):

    temperatures = capabilities['temperatures']

Additional info:
I opened the my.tado.com site and had a look at the json result from the GET request to /zone/0:

{"type":"HOT_WATER","canSetTemperature":false}

As you can see it is for hot water and doesnt contain a temperatures array like the code is expecting

Is this still an issue in 0.58.1? I've setup my tado without an issue and it created a climate.heating and a climate.hot_water.

On the my.tado.com page, I have a Heating and a Hot water configuration.

Yes, it is an issue for me in 58.1. @wmalgadey , are you maintaining this? Otherwise I might submit a PR. I think for now, a simple check to exclude the device if type = HOT_WATER. Longer term, we may want a different device type. The challenge is that hot water can only be turned on or off. No other data is provided. Thoughts?

[dasos]

@michaelarnauts - can you control the temperature of the hot water in app?

[wmalgadey]

Hi dasos,

I am quite busy in the moment. So, if you could make a PR this would be awesome!
