More sensors!

[Fettkeewl]

Is your feature request related to a problem? Please describe.
I'd like to be able to automate and configure UI based on the value of

• Electric heater (if its enabled/disabled)
• Target temperature on Normal/Cooling/Economy mode

Describe the solution you'd like
Create 4 new sensors that display the state of the above mentioned data
(or make the heater a switch if possible, that is "unavailable" unless maintenance PW is provided)

Describe alternatives you've considered
I've manually set temperatures for the different modes in UI elements, which
requires manual syncing with the settings in my LOKE-01

Additional context
Add any other context or screenshots about the feature request here.

Services for target temperature are implemented in v4 release

I've been a bit reluctant to expose stuff from maintenance page until now, the potential for user to f**k up and potentially destroy the house with mould by overpressure. Disabling the electric heater may cause the system to shut down if supply air temperature alarm triggers, leaving the house without ventilation. The initial scope of the integration was not to alter the system settings.

Another issue is flash wear on the system if the configuration is altered frequently
I'll consider it though.
