What's happening? 🤔

I have a stack of 4x14kWh LifePO4 batteries in parallel, controlled by 4xBMS Seplos v. 2, using 4 HUBs of the BMS Connector running on a Raspberry Pi4 with Homeassistant through the ports USB0, USB1, USB2, USB3: I configured 4 HUBs (Pack1, Pack2, Pack3 and Pack4) on BMS connector; each HUB acquires 193 entities from its own Seplos.

So for each HUB in the home assistant dashboard I show: -Current, -Voltage, -SOC% then for each HUB I add and display the totals of: -Residual Capacity, -Rated Capacity -(Rated Capacity -Residual Capacity) In total I use 20 entities and show 15 of which 3 are calculated. I disabled all the other unused entities of the 4 HUBs. So of 193x4=772 entities acquired by the 4 HUBs, I only use 20 of them, the others are disabled.

I) Unfortunately the dashboard is unable to show any of these 20 entities, which are: "not available".

II)Naturally even with all 772 entities enabled, the dashboard does not show these 20 entities which are all "not available".

III)If in the BMS Connector configuration I disable at least 2 HUBs (it doesn't matter which ones), then the dashboard shows the correct values of the two HUBs not disabled.

lV)If I disable polling of at least 2 HUBs in the BMS Connector configuration, then the dashboard shows the "static" values of the entities of the 2 disabled HUBs and the "dynamic" values of the remaining enabled entities.

I imagine there is a sampling time problem in the case of a high number of entities transmitted by each Seplos BMS.

Do you have any chance to fix this problem with 4 HUBs configured? Thanks for your attention.

Sounds like this is probably a naming conflict within the code, different USB entries fighting over the same entity id's as I don't think the USB port was included in the names. I have started to add the USB device to the unique IDs in the new release

[ornolio]

entity names contain packs number (Pack1, Pack2...), so they should not overlap. (see picture).

Right now I'm not close to battery stack. I'll do it in a few days.

Best Regards. p.

I installed the test version: https://github.com/flip555/bms_connector/releases/tag/v1.1.0-TESTING-ONLY it works with 3 HUBs, the 4 one turns all the entities of the 4 HUBS into "unavailable".status.

Thanks. The test version only has about 20 sensors added per hub/pack at the moment the rest would be Unavailable as they are not being provided.

Looking at what you have I'm pretty sure you'd have to delete/disable and re-add the entries but all ID's have changed in the code at the moment.

Trying to work out the best method to name them so they don't overlap, I think it'll be best to reimplement the custom prefix again like you have Pack1 Pack2 as its much tidier than trying to autogenerate everything as is in the test version.

I'll spend some time changing it back to user defined prefixes and release a new test version.

Thank You Sir,

meanwhile I still continue investigation on my problem. I would like to perform some more tests concerning Raspi4 USB hardware power drain when all 4 USB ports have RS485 to USB adaptors plugged in, although PI power supply provides 4A.

Awaiting for any news. Best Regards.

Problem is due to low power of RASPI USB ports when 4 adaptors RS485 to USB are all plugged in.

Even if RASPI PI4 has been powered with a 4Amps power supply.

I solved this issue adding on top of Raspi a USB HUB HAT found on Amazon self powered by an additional.4Amps p.s. .

BMS Connectir works like a charm.
