Hi all
I have created 2 integrations, which can be installed via HACS Custom Integrations, for Hanchu Inverters running Hanchu Batteries.
One is a fork of the Hanchu led API Cloud integration, which is awaiting official HACS integration but can be obtained via custom integration. The Hanchu led integration had some very basic information & only allowed any update via a Lovelace card, so was not easy for any automation processes including being used in Predbat, for those who wanted this.
My version adds extra write functionality, which allows automation & use in Predbat.

The second HACS Custom Integration tries to give similar functionality via a local Bluetooth call to the inverter. However, it does have a number of limitations, which is listed in the Read Me file. In addition, it was tested on a specific hardware/firmware combination (HC:L110 unit with V610 firmware) and that feedback on other hardware variants is welcome. Finally, there is no Hanchu led integration for this Bluetooth version & I must give thanks to blustery7752 who first produced a read integration, which this is based on and 1ulk who expanded the available information & write actions via a web based function.
