Warning Hoymiles Firmware V2.00.04 - hoylabs/OpenDTU-OnBattery GitHub Wiki

Member LinuxUnix80 reports:

DO NOT update your inverters (definitely applies to HMS-1600, HMS-1800 and HMS-2000) to version 2.00.04.

At least not if you are using DPL. As long as the active power is below 100%, everything is fine. However, if a request is made to go to 100% power, this is displayed in OpenDTU, but the output power remains at the last value!

Only a new manual setting regulates the output power again.

I have now downgraded to version 1.1.12. Now everything works as usual again.

If you have set the output power to a fixed value, you won't have any problems.

Btw: Message 223 is no longer reported with version 2!
