Rejected at scanend

[fabianpk]

I am running Home Assistant on a Ubuntu Linux machine. Home assistant is installed using virtual environment. I also have three Plejd dimmers installed, which works when I connect to them with the iOS app. I extracted the cryptokeys and removed the "" before and after the key and added it to my configuration.yaml.

I get this error message when I added the debug flag to the logging. The final message "Rejected" sounds to me like the cryptokey is wrong, I added my configuration.yaml at the bottom. The addresses in the first few lines when it reports "failed connecting" does match the Plejd dimmers.

configuration.yaml extract:

light:

• platform: plejd crypto_key: !secret plejdsec devices: 11: name: trappa1 12: name: trappa2 14: name: trappa3

I extracted the cryptokeys through ibackup viewer and did like the readme:

cat site.json | jq '.PlejdMesh.CryptoKey' | sed 's/-//g'

parse error: Invalid numeric literal at EOF at line 1, column 18688
"5FB3B****************************19CA4"

The above string is what I put in my secrets.yaml but without the "". I tried with the "" as well just to be sure but that didn't work either.

Any help would be much appreciated.

Does it behave exactly like that on every try?

The 'scanend' failure is something internal to bluepy failing as it tries to stop the scanning and start over, not related to plejd at all. The real error is that it fails to connect to both plejds it finds, I think it will fail to connect if you have an active connection from a phone at the same time, maybe try killing the plejd app?

That solved it, thanks. Killing the plejd app and disabling bluetooth on my phone (just to be 100 % sure), and then rebooted Home assistant solved it. I do get some strange things in my log. Just FYI, it works to turn off and on.

After 23:05:00 I didn't do anything. Could this be due to the fact that I have three switches which I associated in Plejd to control one light bulb (which is in a staircase)? Only one of them is actually connected to the lamp, so I'm assuming some inter-device communication is necessary.

Thanks alot anyway!

Yeah, the plejds have some traffic in communicating the current state. Great that it works better now!
