WLANThermo for Home Assistant

The WLANThermo bbq thermometer (https://wlanthermo.de/) uses a local wifi and optional MQTT server to push the temperature changes to.

Setup MQTT in WLANThermo

Link your WLANThermo to the same MQTT server which Home Assistant is using. You can do this easily on the provided web interface.

Home Assistant Configuration

There are three different packages available:

• wlanthermo: Integrates sensors and settings into Home-Assistant
• wlanthermo_push_notify: Adds automations to notify a service upon reaching max/min limits of a channel. Please adapt wlanthermo_push_notify/wlanthermo_automation.yaml and replace the called service: service: notify.mobile_app_sm_g970f
• wlanthermo_timer: Adds sensors, notifications and settings for estimating time left to reach set target temperature of a channel

The packages can be added within the Home-Assistant configuration.yaml:

homeassistant:
  # Include packages
  packages:
    wlanthermo: !include_dir_merge_named wlanthermo
    wlanthermo_push_notify: !include_dir_merge_named wlanthermo_push_notify
    wlanthermo_timer: !include_dir_merge_named wlanthermo_timer

In wlanthermo/wlanthermo_mqtt.yaml and wlanthermo/wlanthermo_template.yaml adapt the MQTT topic of your WLANThermo: state_topic: "WLanThermo/MINIV3/status/data", state_topic: "WLanThermo/MINIV3/status/settings" and topic: WLanThermo/MINIV3/set/channels. Change WLanThermo/MINIV3 to match your main topic and device name.

Home Assistant Lovelace

wlanthermo_lovelace.yaml contains an example how to integrate all three packages into the Home-Assistant frontend:

The lovelace example depends on a couple of custom components:
