Huawei SCharger-22KT-S0 - working

[ra666ack]

Dear Community,

please be informed, the recent firmware V100R023C10SPC220 for the Huawei SCharger-22KT-S0 (finally) supports OCPP (it needs to be enabled and setup in the Fuson Solar App). The OCPP integration enables 52 entities, some of them are not supported by the charger. However, basic control, diagnosis and monitoring works well. ra666ack.

hello ra666ack,
I would like to kindly ask if you could share the latest software with me.

I would also like to confirm and use your OCCP function.

Thank you very much.
V100R023C10SPC220

best regards
Markus

Hi Markus, I got the firmware here: https://photomate.zendesk.com/hc/en-gb/articles/11769399891741-FusionCharge-SCharger-7KS-S0-SCharger-22KT-S0. ra666ack.

Thanks for the quick reply.

I'm familiar with the site. It just didn't show up in Google search results. ;)
I received the software from the vendor a year ago.

Back then I couldn't install it,

but today it worked on the first try.

Crazy.

Now I just need an OCPP server for my Raspberry Pi.

many thanks

Hi Markus, in case you haven't experienced the issue yet, once you configure the OCPP functionally in the wallbox the surplus charging controlled by the EMMA will stop functioning. The only way back is a full reset to factory defaults. In addition it's not possible to downgrade the wallbox to 120 or 020 version... ra666ack

Hello and Happy New Year,

Have you experienced that after enabling integration in HA and setting up charging point (as stated above) the entities become unavailble after some days? The communication with the wallbox, via OCPP, is lost and then a re-configuration is required on the wallbox to start working again. Working with FW 220.
