Am I looking for a standard, accessible API, commitment standards to access?
I have to buy into battery and inverter tech soon…before I get up to speed with HA but I want to ensure I can link them
You must log in or # to comment.
Depending on the capability of the devices, yes, look for existing open standard protocols like MQTT, RS232 / RS485, Modbus, etc
You might need a device between the inverter / battery management system to convert to something that HA can read (ie a serial I/O port)
If you’re only wanting to read the energy, there are other choices like using current clamps with something like EmonPi from OpenEnergyMonitor - this is what I’m doing as my inverter is just not practically accessible.
Goodwe is what has been fitted but the app is neutered and I dont have admin on my unit which is BS. I was looking at others and they have integrations but, is there anything that means I have access forever or could it always be taken away?
I aim to have nothing online, only feeding to HA and tunnell into that from two phones.
I don’t recall what we have, but the installer kindly set us up to report our usage to the chinese company so we could use their app.
Needless to say, after commissioning I blocked it’s internet access.
I didn’t bother with trying to read the data from the unit, I just went with the EmonPi which feeds direct into HA, so I’m 100% in control of my data and my energy.
That looks good, I guess with the inverter it is only monitoring. The Heat Pump one looked good too but I would probably like to be able to manage not just monitor.
How easy did you find setup?
While you’re searching for batteries (or any other potentially smart appliance), check if they are supported by just searching for “device home assistant”
Those that have official support will have a page on home-assistant.io and scrolling the description will tell you if it’s controlled locally (preferred) or via cloud polling/API (less preferred)
Some devices may have custom integrations you can setup from Github via HACS, where the quality and support can vary more significantly than official integrations.
I think some tech can speak open protocols like MQTT. Other than that you’ll have to google whether they require some cloud, and if there’s HA support.
Yeah, I am having trouble grasping what is integration, app or accessible. I am dreading buying something big only for it to not connect.

Sorry, only one of those matches a ‘B’. Maybe two.
