It does not decode SML anymore #4584

Closed NihilUnum closed 1 year ago

NihilUnum commented 1 year ago

The problem

Since couple of Days I can only see uart_debug messages but no SML.

Which version of ESPHome has the issue?

2023.5.5

What type of installation are you using?

Docker

Which version of Home Assistant has the issue?

2023.6.1

What platform are you using?

ESP32

Board

esp32dev (esp32-s)

Component causing the issue

I guess sml platform(?)

Additional information

This uard_debug looks actually right but I have no Idea why is he not decoding in SML I hope this is my issue, it should be easier to solve ;)

NihilUnum commented 1 year ago

I find out that 77:07:01:00:10:07:00:ff:01 is my "Actual Power". And it is in my uart_debug. So I get that Information, but I don't understand why I don't get this decoded.

NihilUnum commented 1 year ago

I will continue my monologue. It looks like my SGM-C4 bidirectional electricity meter got a new firmware(?) With uart_debug I am getting the right data (see http://www.schatenseite.de/2016/05/30/smart-message-language-stromzahler-auslesen/) Is it possible that ESPHome don't work with Ptotocol: SML EN 62056-22?

NihilUnum commented 1 year ago

Looks like I am not the only one https://github.com/esphome/feature-requests/issues/1041#issuecomment-1379847580

NihilUnum commented 1 year ago

No more necessary. Tasmota with MQQT did it with same hard ware, what ESPHome couldn’t.
