Cooktop Integration

[kapps7]

Hi and thank you very much for the home bridge add on.

I have a cooktop BOSCH PIX631HC1E and it has been connected via the plugin into HomeKit.
I wasn't expecting to turn it on of course but I was hoping to turn it off. Is that an API limitation ?
If that's the case, what are people using the add on for. It seems that it's probably more useful for non cooktop appliances.

Thanks

The available functionality is listed in the project README:

• Hob:
  • Control alarm clock and child lock.
  • Monitor power, remote control, and general operation status.
  • Automation triggers for finished, alarm clock finished, and preheat finished.

These are API limitations - supposedly for safety reasons. As you say, this plugin is more useful for other appliance types where the API does allow a useful level of control.

On the specific issue of controlling Cooktop/Hob power, this is what the API returns:

{
  "data": {
    "name": "Power status",
    "key": "BSH.Common.Setting.PowerState",
    "constraints": {
      "allowedvalues": [
        "BSH.Common.EnumType.PowerState.Off",
        "BSH.Common.EnumType.PowerState.On"
      ],
      "displayvalues": [
        "Off",
        "On"
      ],
      "access": "read"
    },
    "type": "BSH.Common.EnumType.PowerState",
    "displayvalue": "Off",
    "value": "BSH.Common.EnumType.PowerState.Off"
  }
}

Note the "access": "read" which indicates that the API only indicates the power status but doesn't allow it to be changed (it is "readWrite" for most other appliance types).

Thanks and completely identify with your comments being API limitations. These ofcourse coincide with the Home Connect app.
No doubt they are in place for safety reasons but I find them counter intuitive.

eg. I would have thought that the ability to turn the power off remotely would enhance safety. Even their built in app notification is on when a timer schedule completes. If anything, the notification to alert that a hob is on would be more useful.

It would be interesting to know what automations people are triggering with the cooktop power. At most I can imagine a light perhaps in the kitchen where a home connect extractor is not integrated.
