Hi to all,
I sue HA to manage temperature inside my appartment. Each of the three rooms has an electric radiator that get turn on or off using a temperature sensor in each of the room.
The temperature sensor in the central room is usb powered.
The other ones are battery powered so sometimes (2-3 times per year) they stop working due to the discharged battery.
I’d like to create kind of a sensor which use the real sensor temperature if it is available, otherwise it uses the usb powered one.
Moreover I’d like HA to send me an email every time one of thos batteries need to be replaced.
How can I do that?
Welcome to the forum. In order to help us help you, you need to provide more info about your temperature sensors, like:
- What model are these temperature sensors?
- How are they integrated into HA?
- Do they show a battery entity in HA?
there are at least 2 good battery monitoring community components available;
hacs addon [Custom Component] Battery Notes
blueprint 🪫 Low Battery Notifications & Actions
You can use either or both at the same time, they do similar but different things.
All of this assumes that battery devices are available in HA and they include a battery reporting sensor.
If HA cannot see the device battery status, then it won’t be able to report anything to you.
If so, you can create a time based calendar/reminder to check the batteries at your chosen interval.
