MG SmartHub almost works

[bec-aus]

Hi, I have imported this OCPP package into Home Assistant and used it with my MG Charge Hub. It is version 1.0.0.0.7b107_MG. Everything displays well, and the Reset button works, however I can't get it to update any settings. The 2 examples I've tried are:

• Setting the charging power - I simply can't see what to update to do this (sliding the Maximum current slider doesn't seem to do anything)

• Remotely stopping Charging. Just about anything I try, like changing the charge control toggle gets an error that says: 'Fail to call service homeassistant/turn_off. ProtocolError: Payload for Action is incomplete, {'cause': "'transactionID' is a required property"}

This error message may be from testing some other setting, but ProtocolError: Payload for Action is incomplete, {'cause': "'transactionID' is a required property"} seems to be common to each thing I have tried.

Please advise either any other testing that would be helpful, or how I can remotely set the charging current. (Setting the current through the MG supplied web page does work, but I can't figure out how to automate it to maximise my solar consumption) I have created a helper that tells me the current I want to tell the charger to supply.

I've got a Chargehub and haven't seen the same issue. That's not to say the charger is flawless, it has a lot of software bugs that I have been annoying MG to fix.

Your firmware is old, get this one of this page, https://mgmotor.com.au/charge-hub-support/
Run the update. If you dont see the firmware version reflected in the webpage, flash it again. Mine took a few goes.

Here is a snip of my settings, so if anything looks vastly different.
