v2021.12.2

Breaking changes:

Setting initial_hvac_mode in the configuration YAML will force the selected state upon restart. Remove this setting from configuration to let the thermostat restore its previous state.
Setting target_temp in the configuration YAML will force the set temperature upon restart. Remove this setting from configuration to let the thermostat restore its previous set temperature.

What's new:

• Add PID mode option selectable with set_pid_mode service, to either set the PID in auto (default) or set it off so it acts like generic thermostat.
• Add hot_tolerance and cold_tolerance to set hysteresis for use with PID mode off.

Bug fixes:

• Missing hot & cold tolerance #43
• Thermostat doesn't heat after boot while temperature is below set point #41
• Log filled with warnings about entity implementing device_state_attributes
• PID is refreshed on every temperature change with sampling_period defines #40
• Attributes are not updated after a calculation #39
• Integral part of the PID controller accumulates gain for error during the period the thermostat was in OFF state #38
• Unresponsiveness initial_hvac_mode: "off" #37
