How can I read data from an older Renogy Remote Control Module (LCD, no BT)?

We have an old 12v Renogy 2000 watt pure sine wave inverter with the original LCD remote control module plugged into it. I’m wondering if anyone might be aware of a way to tap into the data stream?

I do not believe that the newer Bluetooth modules will work with this older inverter charger.

This older system is going to be moved to a garage area and updated as it fails. I’d like to find a way to monitor it via my existing HA set-up, if possible.

Does this help?
