Question: Advanced Diagnostics for BMS #30

Closed Ne0-Hack3r closed 1 year ago

Ne0-Hack3r commented 1 year ago

Thank you so much for this custom integration. It works very well with HA and my Delta Pro units.

I was wondering if there are any plans to expose additional sensors from the BMS in DP or EB units such as battery pack voltage/current and/or individual cell voltages (if available)?

We were planning to respond to your request.

If you list the entities you need here, we will consider it.

Here are the detailed sensors I believe it would be nice to have for advanced battery diagnostics...

battery_level battery_voltage battery_current battery_temp battery_cycles battery_soh battery_voltage_max battery_voltage_min battery_temp_max battery_temp_min battery_mos_temp_max battery_mos_temp_min battery_fault battery_in_power battery_out_power

Obviously it would be good to have this information for the entire battery bank but it if is possible to extract the data and have sensors for each individual battery cell that would be very good. This would help in determining if there is an issue with a single cell and also to chart the health and behavior of the cells and the entire battery pack over time.

Thank you for considering this enhancement.

Certainly the usage you suggest would be very useful in some cases.

However, there is one problem. The maintenance cost would be much higher.

It would take a lot of effort to make sure everything is correct, as the units may differ from model to model, and you would have to add a large number of entities and keep maintaining them over time.

We'll be ready to implement these things, but I think it's best to wait until we get more people's opinions before deciding whether to release it or not.

I will move this Issue to Discussions once. If we get a certain number of votes there, we'll finalize the release.
