First byte of encrypted telegram should be 0xDB

[theFeverDog]

The problem

After updating to ESPHome 2021.10, the DSMR component does not seem to decrypt data from the P1 port correctly any longer, as I get the following error message:

[E][dsmr:090]: First byte of encrypted telegram should be 0xDB, aborting.

The integration worked correctly with version 2021.09.x.
The decryption key is set in the secret.yaml. Updating the key using the service call ESPHome: slimmelezer_set_dsmr_key does also not work.

Which version of ESPHome has the issue?

2021.10.1

What type of installation are you using?

Home Assistant Add-on

Which version of Home Assistant has the issue?

2021.10.6

What platform are you using?

ESP8266

Board

slimeleezer

Component causing the issue

DSMR

Example YAML snippet

uart:
  baud_rate: 115200
  rx_pin: D7

dsmr:
  id: dsmr_instance
  # For Luxembourg users set here your decryption key
  decryption_key: !secret decryption_key

Anything in the logs that might be useful for us?

Only one error message is reported over and over in the log:

[E][dsmr:090]: First byte of encrypted telegram should be 0xDB, aborting.

Additional information

This is using a Luxembourgish smart-meter, so the data of the P1 port is encrypted.

Hey there @glmnet, @zuidwijk, mind taking a look at this issue as it has been labeled with an integration (dsmr) you are listed as a code owner for? Thanks!

Setting crc_check to false seems to allow decryption to work again.

However, after 20 minutes the board became unresponsive, currently trying again after a restart...

You might try the fix mentioned in this issue:

#2577 (comment)

this is: setting "rx_buffer_size: 1000" under "uart".

I cannot vouch for it because my meter does not use encrypted data, but it did show packet loss which might explain your observations.

[theFeverDog]

Thanks, I actually tried both " rx_buffer_size: 1000" and "crc_check: false" initially.

To see which of the two had the effect, I disabled the rx_buffer_size again, and decryption still works. So this seems to be related to the default crc_check not working for encrypted streams.

[theFeverDog]

Another update: while all sensors are updated after power cycling the board, no subsequent changes seem to be registered, e.g. values for power consumed, energy consumed and gas consumed did not update during the 60min after my last power cycle.

I've been working on a fix for CRC errors with the unencrypted DSMR variant.
This can be found in this issue: #2577

I'm wondering if the kind of issue that I tracked down there, is also responsible for the issues that you are seeing with encrypted DSMR. Therefore I implemented the same kind of fix for the encrypted telegram reader code.
I can not test this code myself, because I don't have a crypted smart meter. Can you guys please test if this makes any difference for you? You can test out the fix by adding the following to your device YAML file.

external_components:
  - source:
      type: git
      url: https://github.com/mmakaay/esphome
      ref: fix-crypt-mdsr-chunked-reading
    components: [ "dsmr" ]
    refresh: 60s

Please uncomment or remove the rx_buffer_size if you have added that one. My target is to have the telegram reader work with the default buffer size.

Note: you still might see "First byte of encrypted telegram should be 0xDB, aborting" messages in the log. This would occur when the reader misses the start of the encrypted telegram. For example when booting up the reader device, in which case the reader might simply start reading in the middle of a telegram. The message might even occur a few times in a row. IMO the logging on this could be made a bit friendlier, but that is not the first focus now.

[theFeverDog]

Sorry for getting back to you so late, I just got around to testing your fix now.

I used the external component as indicated, disabled rx_buffer_size and crc_check: everything is decrypted correctly and updating regularly!

(The data not updating I experienced earlier could also be linked my not having set a baud_rate: 0 for logger as indicated here ##2621. Indeed the data now seems to update regularly every 10 seconds)

[mmakaay]

Awesome! Thanks for testing this, @theFeverDog
I'll see if we can get these changes incorporated in ESPHome.
I already have a PR for the unencrypted DSMR version. I'll either extend that one, or I will create a PR after that one is merged, to not have too many changes in one PR.

[Brillie]

@mmakaay Maybe I'm a bit late to the party, but I too can confirm your fix to work perfectly -- without changing rx_buffer_size or crc_check. No errors in esp logs in the past couple of days, sensors update every second.

Hi - here are the Infos for the problem with Siemens IM350 Smartmeter:

I was never able to use EspHome for this to read encrypted data from this device.
Other firmware/project works with same hardware (but I use D7 (GPIO13) and a different circuit):
