HeaterMeter smoker controller component for Home Assistant

HeaterMeter smoker controller integration for HA.

BREAKING CHANGES:

• The sensor previously reported "-" when an alarm was disabled, and the "update_heatermeter_input_numbers" script would update the alarm values in the UI to "-1". I've changed this behavior, and now the senor values match what is in heatermeter. You will need to update your "update_heatermeter_input_numbers" script accordingly. I've updated the example in the scripts.yaml section of this readme. The benefit to this is that those values in heatermeter survive a reboot, so if you always use the same alarm values, you can save them and just toggle them on/off by making the number negative. Example: Probe1 Alarm = 203, to disable the alarm (but retain the value) you can set it to -203. If you prefer the legacy -1 values to represent a disabled alarm, you can find an updated script in: "legacy_update_heatermeter_input_numbers.yaml"

Changes:

• Fixed depreciated constants (TEMP_CELSIUS/TEMP_FAHRENHEIT) to UnitOfTemperature
  • (legacy constants to be removed in 2025.1)
• Negative Alarm values are sync'd (rather than displaying -1).
• Updated YAML to include default values for INT and FLOAT values in templates.
  • See 2021.10 Breaking Changes\Templates
• Added 'Update HeaterMeter Alarms' automation (Contributed by Chris8837).
• Removed Refresh button from Alarms card (not needed with the sync alarms automation).
• Added 'heatermeter.set_alarms' and 'heatermeter.set_temperature' scripts for setting & refreshing alarms.
• Added 'Alarms' card to ui-lovalace.yaml.
• Added 'automation.bbq_is_ready' automation to announce when your food is ready.
• Added High/Low Alarm Sensors for each probe.
• Added 'set_alarms' service to set probe alarms.
• Fixed Issue #1 'Fill Example Data inserts parameter twice', removed parameter from service example.
• Temperature units automatically set based on 'Unit System' setting in 'Configuration\General'.
• Removed username and password configuration options, use api_key instead.
• Added an Alarm sensor that changes to 'on' when any probe's Alarm/Ring value is set to a non-null value.
• Added an Automation example to send push notifications w/ action to mobile app.
• Changed the 'lid' icon to mdi:room-service because it looks more like a BBQ lid.
• Changed the Input_Number's icon to mdi:target.
• Changed the default heatermeter.set_temperature to 225.
• Modified the script.yaml by removing the trigger. (Set Point will be set manually in the Lovelace card).
• Lovelace Card Updates:
  • Now includes a card for setting the Set Point with a slider and 'Set' button.
  • Added history graph for the fan.

✔️ ToDo:

• Stop the integration from spamming the logs when the HeaterMeter is offline. (Thanks spoetnik)
• Implement scan_interval.
• Make TEMP_FAHRENHEIT / TEMP_CELSIUS a user configurable option. or read it from the HeaterMeter config.
• Home Assistant Discovery
• Individual probe Hi/Lo alarms.
• Create service to enable/disable 'Ramp' mode. (HeaterMeter API doesn't support this)

Notes:

• Change 'service: notify.mobile_app_<YourPhone>' to match your notification service.

Notes:

• In the 'heatermeter_change_set_point' script, change the data_template: temperature int(225) to natch your desired default set point. (This shouldn't be necessary as long as the corresponding input_number 'initial' value has been set)
