The problem

When I try to set the cooling temperature to 100 F, I get the error "Provided temperature 100.0 is not valid. Accepted range is 44.6 to 95.0." (This corresponds to 7 to 35 C.) But the Insteon can be set to a higher temperature than that. I am told that the fix for this is for the integration needs to provide setpoint limits, because currently it's just using 7 to 35 C because that is the Home Assistant default range for integrations that don't set the limits.

By the way, in order to make the UI allow me to attempt set a higher temperature, I had to set min_temp and max_temp in the Home Assistant YAML config.
