Compatibility with DIEHL LNE6250

[Anoxym]

Hi,

Is this project could work with this water meter :

Thanks

[SzczepanLeon]

99% to yes

[Anoxym]

Great thanks I'll try :)

[g0mml]

I have the same meter as you and I was able to get the meter ID using the the 🛠 ESP32 Test configuration. The transmitted telegram contained all the data. I'll now try to use the more complete examples...

[Anoxym]

Hi,

I try to deploy the esp32 test on my esp32 with ESPHome on Home Assistant but it won't work, I don't understand, can we have a minimalist code to get the ID ?

[SzczepanLeon]

Please read informations on my main repo page. Minimal YAML is described there.

[Anoxym]

Did you have a working esphome configuration to get the ID ?

with this :

wmbus: all_drivers: True log_all: True

What did I need to get a working code ?

[zibous]

for izar watermeter:

https://github.com/zibous/ha-watermeter/blob/master/esphome/testcases/wm-esp32-izar-test.yaml

[Anoxym]

I have the same error :

[SzczepanLeon]

Userfriendly solution is ongoing:

[Anoxym]

It works adding "platform: esphome" :

ota: platform: esphome password: "wmi01-testcase" on_begin: then:

• logger.log: format: "OTA Start" tag: "OTA" level: WARN on_progress: then:
• logger.log: level: WARN tag: "OTA" format: "OTA progress %0.1f%%" args: ["x"] on_end: then:
• logger.log: format: "OTA End" tag: "OTA" level: WARN on_error: then:
• logger.log: format: "OTA update error %d" tag: "OTA" level: ERROR args: ["x"]

We need to be close to the watermeter to get ID ?

Can someone help me with the code :

There is errors and I don't know why, maybe esphome can't get to wmbus ? :

[SzczepanLeon]

source: github://SzczepanLeon/esphome-components@main

If you want to stay with this YAML format, then replace main with version_3

[Anoxym]

Same errors but the url with @version_3 works

[Anoxym]

I found the error and managed to upload the code to ESP. On Home Assistant I can show the Water meter but entities are Unknown :
