Hey, me again. I’ve updated the blueprint to use EVENT mode instead of COMMAND mode after looking at another blueprint that seemed to have luck with that.
Hopefully it works for you this time.
Hi
Thank you for the cool blueprint. I watched the youtube video and I like the knob work. But I have zigbee2mqtt and when automation is triggered an error appears
Stopped because an error was encountered at 1 veresnya 2023 p. o 17:59:06 (runtime: 0.01 seconds)
UndefinedError: 'dict object' has no attribute 'to_state'
Tried different command and event modes without success.

Hi, I have tried to use this blueprint to make an automation and I get the error:
Message malformed: Unknown entity registry entry dc2875e62569a54fbbe9bc9ba5c9613f
I can add automations manually but I cannot use the blueprint.
Is there anything I can try?
Greg
Did you solve it? 
I just tried this blueprint and I have the same error when trying to create the automation.
Did you managed to find a solution for this?
@nwithan8 , any idea what causes this error?
LE: nevermind, it seems that I found the problem (or at least the source of the problem and a workaround for it)
The problem was with the trigger using the device. So I changed the trigger to be an entity of the Knob and added another input in the blueprint to be able to set the name of the device (fridnely name in z2m - not very nice since is a free text, but still works).
I also changed the order of the modes (seems more natural this way):
- Mode 3 for color loop
- Mode 4 for Hue loop
Here is the code

When using the blueprint I get the same error, I tried your blueprint with the edits but nothing seems to be working… any ideas how I can fix this, im using the rotary knob through Z2M
Update: Changed the knob naming field to the device name without using capital letters, this made the whole system work, I also changed the single press to toggle the lights and the hold function to switch modes, this makes more sense to my family members who will be using the controller, this prevents accidental mode switching.

Hmm.
Yes unfortunately having the same issues regarding the unknown entity and can’t seem to work out a fix for it. Shame as the YT vid looked great.
Ah well, back to the drawing board.
Hello,
Would you mind sharing your edited blueprint ?
I tried everything to my understanding but I can’t even get a trace on the automation which would help me to debug it. I tried to fix set the state of the knob action entity but it didn’t even work too. So I’m guessing the automation do not succeed to read the entity properly but I can’t understand why.
Here is my automation:
alias: test
description: ""
use_blueprint:
path: nwithan8/ers_rotary_dial_light_control_z2m.yaml
input:
light: light.lb2_bedroom
dial: sensor.klb_bedroom_action
knob: klb-bedroom
mode_tracker: input_number.dial_mode_tracker
color_tracker: input_number.dial_color_tracker
hue_tracker: input_number.dial_hue_tracker
brightness_tracker: input_number.dial_brightness_tracker
The blueprint has been updated with @chelule code above.
Thank you to anyone willing to help, I’m a bit lost on this one.
Okay got it to work, I etited the behavior a little:
- Added a “default profil” you can activate when rotating left while pressing the button 2000k and brightness 255.
- Added the " color" profile you can activiate when rotating right while pressing the button, it will apply the settings you previously used with the knob.
- After being inactive for 3 minutes (no knob activation for 3 minutes) the automation will reset to mode 2 which is brightness since it’s probably the most used
- Switch color & hue so hue is now mode 4 and color 3
- Switched to long press to switch between profile and short press in order to turn on & off
Everything should be working by now using the knob action entity.

hi I tried your blueprint and all it does is on and off. What could be the problem?
Tried both, ZHA and Zigbee2MQTT but none worked! ZHA nothing happens. Zigbee2MQTT the BP doesnt save. I get the error:
“Message malformed: Unknown entity registry entry 093db2abe9da681067b3835b4bbe70eb”
Same with my installation!
I have the same problem here
Hello Nate (@nwithan8 )
Thank you very much for this BluePrint…
Like some of us, I have the same issue related to device ID.
Do you have any idea/suggestion to debug it?
Thanks in advance

Hi,
Did someone managed to find a solution for the “Message malformed: Unknown entity registry entry 3f54bf4ca3825e82d62ae23dc093a929” error?
Looks like some nice mods to an already cool project. I was excited to find this stuff after picking up one of these knobs, and plan to do some testing this week.
I was just thinking, would it not be a good feature to have a mode to jump between a list of scenes as well? It seems like it would be a time-saver and a handy feature for many people. Personally, I have a few color setups in each room that I stick to, and I’m unlikely to set all of my lights and LED strips in a room to the same color. Sorry if it’s a dumb idea – just brainstorming.
Thanks
EDIT: Yep. Doesn’t even work. Bummer.
