Support reading of multiple values at once.

Did you read the instructions?

• I have read the README.

The request

I simply tried to read multiple values and it worked. I documented it here.

Additional information

No response

Thank you for sharing, this would be a really nice improvement

In the current implementation, the sensors are defined in const.py https://github.com/golles/ha-kamstrup_403/blob/main/custom_components/kamstrup_403/const.py#L30-L320
And the protocol is defined in https://github.com/golles/ha-kamstrup_403/blob/main/custom_components/kamstrup_403/kamstrup.py

At the moment __init__.py loops through all sensors defined in SENSORS.items() and calls readvar for each one.

The new way would be to pass SENSORS.items() down to new function readvars which prepares a single request for all sensors. The new request would look like:

3F 10 <numSensors> <codeOfSens1> <codeOfSens2> <codeOfSens3> ...

And the single response needs to be taken apart matched to each sensor:

3F 10 <codeOfSens1> <respSens1> <codeOfSens2> <respSens2> <codeOfSens2> ...

See this example for how to request 7 sensors at once and how to decipher the response.

Thanks, my previous comment was supposed to go to #31 (sorry for that)

For now, I marked this as a nice to have in #30. If I won't make it in that PR, I'll do it in the next one
