This flow allows to create a messaging system for low batteries notification in Home Assistant quite easily. You don’t need to add a new notification service for a new battery device anymore.
I have implemented different notifications for three type of battery powered devices. Note: You have to follow some naming convention for the devices to make it work this way.
- Thermostat Heating Battery
- Thermo/Hygrometer Zigbee
- Mobile devices
Note: The flow is heavily inspired by this Youtube video: https://www.youtube.com/watch?v=qySk43zMUzs&t=600s
