Hi. Maybe someone know that HinaESS PowerGem Plus 14,3kW can integrate with Home Assistant via RS485 or CAN?

Thanks

@sarzyk ,

I don't know the HinaESS Powergem Plus batteries, but a quick google reveals that the ports looks like this:

Weirdly, the manual does not identify what port the one between port 7 & 8 is, but my guess would be that is a RS232 port with a 6 pin RJ11 connector.

Looking at some of the other HinaESS 5kW batteries, the port layout is similar to yours , but more familiar to the standard "Pace BMS" layout.

So you may be in luck that your bigger battery also has this BMS.

To test, get yourself a RS232 (with RJ11 plug) to USB cable, install PBMSTools program (RS232 version) on windows computer, and see if it responds.

Even if it doesn't, it may just be that the signals on the RS232 port is not standard, as I found out when trying to get info out of an Eenovance (OEM Sunsynk) battery. Is also has a PACE BMS, but standard cable didn't respond. A quick changeover tester (RJ11 male to RJ45 female) gave me the correct response, as the RS232 port on that PACE BMS is not wired standard.

Hope this helps.

spelling!

Try my united bms framework for create custom modules for your battery : https://github.com/mamontuka/ritar-bms-ha its not hard, read manuals, catch registers, create map, ajust parsers

I have the Powergem Max 16kWh battery and I got it to work with Home Assistant over RS485 cable. I imagine it is similar to the Powergem 14kWh battery. The Powergem Max 16kWh battery uses a Topband BMS that responds to PACE-protocol commands (PACE BMS).

You can review the code in the GitHub repo and go through the Readme.md file to see how to use it and check if it works with your battery.

HinaEss provides the wiring diagrams for the RS485 cables on their website and you will need an RS485-to-USB adapter to connect it to a Raspberry Pi or something.

I unfortunately don't provide support for this code as it was made really just for me to get this working. Hopefully this helps others out there who are trying to get this to work.
