Hi,

im a great fan of opendtu. I heard that Hoymlies released a new Firmware with mqtt.

The Hoymiles MS-A2 gained MQTT capabilities with a firmware update (FW V01.05.xx or later) released on June 6, 2025.

Is there now a possiblity to add the battery storage to the opendtu?

A feature if i understand it correct it is possible to send mqtt commands to the MS-A2 Storage.....and can also modify values....
Regards Raini
