Naming issues for sensors - Duplicate device name / hostname

[luckylinux]

I previously mentioned this issue regarding Battery 02, when upgrading from Syssi esphome-jk-bms to Sleeper85 esphome-jk-bms-can.

I now flashed also Battery 01 in order to have more consistent readings across the different batteries.

The essential problem is that the hostname is repeated in the sensor.xxx access string.

But it's not always the case. Some are, some are not.

I deleted the previous MQTT Device (ESP32 board) after reflashing this one (Atom S3 Lite Board).

YAML file used with Syssi esphome-jk-bms: https://github.com/luckylinux/jk-bms-build-helpers/blob/main/_old/esphome-jk-bms/esp32-ble-2.0.0.yaml YAML file used with Sleeper85 esphome-jk-bms-can: https://github.com/luckylinux/jk-bms-build-helpers/blob/main/esphome-jk-bms-can/esp32-ble-1.17.5.yaml

For reference (since I didn't have screenshots from before apart from those on the DIYSolarForum - will try to include those if I can find them), my weather Station Sainlogic WS3500 via Weewx and using weewx-mqtt reports like this to the Mosquitto MQTT Server:

[luckylinux]

I couldn't find screenshots for Battery 02 having that issue before ...

Maybe related to https://community.home-assistant.io/t/esphome-mqtt-devices-have-duplicated-names/609858/4 ?

[luckylinux]

What's worse is that it's not consistent and even in MQTT it shows one thing, in home assistant another.

I updated the simplified view for now this works, but it's definitively a hack:

I tried:

• Restarted ESP32 of Battery01 (NEVER touch ESP32 of Battery02 / MASTER, otherwise grid goes down).
• Restarted Mosquitto MQTT Broker
• Restarted Home Assistant

That doesn't seem to help. There is something new going on here. Maybe a new library of ESPHome / IDF Framework is used compared to Syssi previous code ? Not sure.

[luckylinux]

It's also even more funky because Battery 01 has some max/min/avg built in, Battery 02 does not ...

[MrPabloUK]

Here's what I would try.

• Remove all JK BMS devices from HA
• Delete all discovery topics related to the JK BMS devices from your MQTT broker
• Restart HA
• Add auto detected devices in HA

[luckylinux]

Concerning point 1: Remove all JK BMS devices from HA. Would they be re-added automatically ? I cannot afford to restart the ESP32 of battery 02 ...

Maybe I'll try your procedure with Battery 01 first.

[luckylinux]

OK Deleted Battery 01 and the discovery topic on the MQTT Server for Battery 01

Restarted Home Assistant -> No joy Restarted Mosquitto MQTT Broker -> Device got auto-detected

But still

Is this related to the issue below?

https://github.com/Sleeper85/esphome-jk-bms-can/issues/46

This has been corrected in the new version in testing phase.

All name and id are unique and prefixed with ${variable}.

Can I close this issue ?

[luckylinux]

Not really.

EDIT 1: From a quick Look I'd say that #46 is for a VERY SPECIFIC set of entities (e.g. ignoring button.jk_bms_bat02_jk_bms_esp32_restart from the Logs, probably because those entities did NOT have an ID "set" in the YAML File at all), whereas the Issue reported here is basically for ALL (or most of) Entities (which had an ID "set" in the YAML File, but it was not unique).

That's the Difference from what I remember at least.

But I guess a bit too much time went by :disappointed: .

EDIT 2: and I think the Issue described here might be (probably also ?) related to previous syssi Code used "directly" (before I knew about your Project I was using syssi Code) and/or Transition from MQTT -> API.

And Probably also Upgrade from one Version to the Other, without first DELETING the existing ESPHome Device from HomeAssistant -> Devices -> ESPHome, thus some Entities were still laying around.

Cannot remember 100%, sorry :disappointed: .

[Sleeper85]

So, I close this issue.

If you still have a similar problem you can re-open this issue.
