HMS-400BM identified as "Unknown" in the inverters.

[creaimmo]

Hello,

I am trying to set up a microinverter with the reference HMS-400BM. It is correctly recognized with a Hoymiles serial number, but once added, it is marked as type "Unknown."

[tbnobody]

Then please Tell us the serial Number (at least the first six digits) otherwise it's not possible to further investigate this

Please also tell us your country of residence and the purchase. I believe we already had one HMS-400BM previously and the idea was that this model is available in some countries only ?

@creaimmo where did you buy this inverter from (dealer / manufacturer) and what is your country of residence?
We still have too little info about this model.

There has been another HMS-400BM in #2170 owned by @tt-why from the company Beem in France.

You may also want to double check closed issues #1540 and #1190 for details on the ChannelChangeCommand.

Buy from BEEM in France

Please add the Hardware and Firmware Version numbers and other details from the Inverter Info (MCU icon) page.

I think tbnobody will add the Beem OEM inverters to the code once we have all the details and you have been able to confirm that most of the data retrieved from the inverter looks plausible?

eg like this

Where to find this information knowing that on the direct page I do not have an MCU icon

Unfortunately it's not that nice. Otherwise it's here:

The problem is, that the mentioned serial number 1400xxxxx is not yet assigned to a inverter type. Without this, it gets not read.
The 1400xxxxx is already known and I will add it in the next release. (Then the MCU button should appear as well)

This explains the problem. When do you plan to make this new version available?
Sincerely

[creaimmo]

Top! We are waiting for the next version

There is the idea to select a matching model from the known list of models when the actual model prefix is still unknown.

You can try it with either 1124 (v1) or 1125 (v2) as a workaround using the currently implemented models:
