add a utility meter to the firmware

[amgstone]

add a utility meter to the firmware to connect to the "Battery" dashboard. So that you can add and see how much went into the accumulator and how much came out.

[syssi]

You can find the solution here: https://github.com/syssi/esphome-jk-bms/issues/80

[amgstone]

I can insert a utility meter into this firmware, gives an error

[syssi]

The configuration looks good to me. Could you explain what isn't working in detail?

[amgstone]

http://joxi.ru/MAjegKyTj5VyX2 battery dont work

[amgstone]

How can I give you access to HA so you know?

[amgstone]

I'm sorry, it's being updated, but the utility meter somehow works strangely, the information is not updated once an hour

[syssi]

Please monitor the behavior over a few days.

[amgstone]

what am i doing wrong? my utility meter does not work.

[syssi]

Could you describe what's not working?

[amgstone]

utility meter inverter does not transmit values ​​to HA. there is a mistake somewhere.

[syssi]

Does the ESPHome node report a value greater zero? Could you provide some logs?

[amgstone]

can you add utility meter in yaml?

[syssi]

esp32-ble-example-plus-energy-meter.yaml.txt

[amgstone]

It works well for me. looked at 12 o'clock resets

[syssi]

If the ESHome node looses the time source it's unable to reset once a day.

[amgstone]

flash and the time will be updated

[robio339]

I thought that i deleted my post fast enough but forgot on email notifications. I did flash this esp multiple times since this happened. I also changed name manually (from ${name} total ... to bms total....) and it went to 0, but after midnight again didn't reset. Yesterday before posting I changed it back to ${name} total .... and after changing entity's in entity card to new ones values stayed the same as with previous entity. I remembered than that the same entity is used in energy dashboard but there the values worked fine all the time. So i deleted entity card, created new one and everything was fine. Values were both on 0 and time on clock was also 00:00 ;). I will see tonight at midnight what will happen. Thanks for replying and keep on good work. Best regards Robert
