# Geiger-interface

### GMC.MAP integration
- Create account on https://www.gmcmap.com/
- Login, go to **My Account** -> **Manage Geiger Counter**
- Go to **Add device**, select location on map, select your model -> **OTHER**
After that you will see **Account ID** and **Geiger Counter ID**

### HomeAssistant integration
After MQTT is configured in Geiger-interface, simply add to HomeAssistant configuration.yaml

```yaml
    - name: "Geiger CPM"
      state_topic: "esp32/CPM"
      unit_of_measurement: "CPM"
      icon: mdi:radioactive
    - name: "Geiger μSv/h"
      state_topic: "esp32/uSv"
      unit_of_measurement: "μSv/h"
      icon: mdi:radioactive
```

reload configuration and voilà!
