Hi again,

is there any plan to expand the available Modbus/MQTT register set for the Orion devices? Right now, it’s quite limited — for example, we can’t even adjust the charge current (A) limit or toggle key functions remotely.

Having more control through Modbus or MQTT would make system integration so much more flexible, especially for advanced setups. It would be great to know if this kind of expansion is on the roadmap.

Thanks for considering!
