Control MQTT topic #176

I have 12 BMS's. I would like them under the same MQTT parent topic of "BMS" and each individual bms device on topic "BMS/1/"... "BMS/2/"... "BMS/2/"........ "BMS/12/ etc

This will enable MQTT wildcard "BMS/+/sub_topic" to be used to test and subscribe to all BMS specific sub topics and perform efficient monitoring

i.e. subscribing to "BMS/+/Current" to monitor instantaneous current across all bms and perform checks

Hope this clarifies - and thankyou for your assistance.

Understood. I've pushed a change that allows slashes in the mqtt topic prefix 2a78513

Try and let me know wether it works

@fl4p Hi - can you commit this update to the HA build please.

Then I can test the modification you have made

Please

This change correctly creates the MQTT topics with hierarchical slashes "/"

But it does not create the Home assistant sensors correctly, in fact no sensors are created at all.

Hi, I would to create the first 9 BMSn with 01, 02, 03 ... 09 and then 10, 11, 12 and so on.
This should be better for the sorting of the BMS number.

I have a Bluetti with 16 serial cells.
I used this numbering for the voltage of the cells.
