I have the same issue. Would like to be able to turn the humidifier off during peak hours for electricity. Thanks!

I would also like to be able to control the Humidity on a th8321wf1001 thermostat. Both the app and the website portal allow this to be viewed and changed as shown in the picture attached.

thanks

My thermostat does not have this feature - I will need some endpoint details sniffed out from the browser. If you can provide the message being sent when you make the changes (via the browser developers debug screens) we can try to add this.

Can you show me what you need? I can grab those. Do I grab the info from the "element" screen of the developer tool? Thanks

In firefox -> view the web page in question, ctrl->shft -> i will bring up the developer pane.
Select the network tab
set your humidity and submit it (I assume submit is like the thermostat interface).
You should see a POST message in the pane. Select the message, right side of pane will show details. Select the Response and Reqeust tabs sharing the JSON values . Also share the host/filename info found on the Headers tab.
You may want to xxx the deviceid if it's in the request/response messages.

Should look something like:
JSON:
{"DeviceID":xxxxxx,"SystemSwitch":null,"HeatSetpoint":67,"CoolSetpoint":null,"HeatNextPeriod":null,"CoolNextPeriod":null,"StatusHeat":1,"StatusCool":1,"FanMode":null}

Headers something like this:

scheme
	https
host
	www.mytotalconnectcomfort.com
filename
	/portal/Device/SubmitControlScreenChanges

Please open an issue here:
https://github.com/mkmer/AIOSomecomfort/issues

This will help me document the changes to the API and ask your further questions outside of HA.
Since this type of "question" is a feature request, the HA issue will probably be closed at some point.
Please attach the discovered information above, and also observe the web page in developer mode and share any GET messages generated.
Something is looking a bit fishy with the Response data - IndorHumidityAvailable: false yet the request has it set.
Thanks
