Just putting it out here.
I’m planning to buy an Eva-power plug-in battery.
One of the things I always look at, is for support in OpenHAB.
Because I can’t find anything yet, I hope someone will take this up to create a new integration fot this.
I’m unfortunatly a very moderate programmer and also don’t have any java knowledge.
I hope to get my set somewhere this month and happy to test the integration offcource!
I would buy a zigbee device. That way it is 99% sure it would work in openHab.
I don’t buy WiFi devices anymore. I use zigbee2mqtt as it is fairly well supported.
It would mean you would need to buy a zigbee co-ordinator.
Just a suggestion.
In general I agree, but there is not always a choice.
Since I think that every supplier for a Plug-in battery will use an app, there is already WiFi.
I don’t expect they even bother to add Zigbee into the device, just for a home automation system.
I’m not sure about the Eva-Power battery, but many other plug-in battery/Power Station manufacturers do include Bluetooth for their own app functionality instead of WiFi, which would also be an option for integration.
