Tried that, but that doesn’t work. If you limit the value to 100 like this and turn the encoder past the 100 limit, it will keep counting. So if you turn right 10 clicks past 100, you would have to turn left 10 clicks, before your value will lower to 99.
In this log I went up 10 clicks and then 10 clicks down again, using your suggestion:

How about this:
- lambda: |-
if (x < 0.0) set x = 0.0;
if (x > 100) set x = 100;
return x;sensor:

return x;
It validates, but won’t compile:

Lambdas are C++ and not validated…I think you’re missing curly braces and/or do you need “set”?
if (x < 0.0) {
x = 0.0;
}tried it like this now:\
- lambda: |-
if (x < 0.0) { x = 0.0; }
if (x > 100) { x = 100; }
return x;
but the issue mentioned here: Rotary encoder dimming
is still the same…
I’m trying the same thing and saw that the min/max values are in the works currently:
So we just have to wait a bit or be brave and try the dev branch.
But the other question is: how do we get the rotary encoder’s value into the PWM output? I’m currently using the config below, but it has problems: the values set with the rotary encoder are different from the values that I can send with MQTT. With step 1 of the rotary encoder the LED is still off, and with step 2 it’s rather bright already. With MQTT I can send ‘{“state”:“ON”,“brightness”:38}’ and get a very dimly lit LED.
This is the config that I came up with:
sensor:
- platform: rotary_encoder
name: "Rotary Encoder"
pin_a: 19
pin_b: 18
filters:
- or:
- debounce: 0.1s
- delta: 10
- lambda: |-
if (x < 0.0) return 0.0;
if (x > 255.0) return 255.0;
return x;
on_value:
then:
- output.set_level:
id: pwm_output
level: !lambda "return x/256.0;"
- logger.log:
format: "pwm_output set to %.1f%s"
args: [ 'x*100/256.0', '"%"' ]
output:
- platform: ledc
pin: 27
frequency: 1000 Hz
id: pwm_output
light:
- platform: monochromatic
output: pwm_output
name: "LED-Platte"
id: led_id
I’m very new to esphome and Home Assistant. Maybe somebody can see what I did wrong?
I’ve not used a rotary encoder myself - but I would set the light brightness rather than the PWM output directly.
on_value:
then:
- light.turn_on:
id: led_1
brightness: !lambda |-
return x / 255;

Thank you, DeanoX, brightness works really good.

[12:56:13]Rebooting...
I already tried the beta and dev channels (with beta, it’s the same, with dev the rotary encoder doesn’t seem to do anything at the moment). I guess I try posting an issue at Github.
A little follow-up on my initial question:
I now have thing set up like this. I’m assuming a value from 0-25 (which can be limited in a future version of esphome)
sensor:
- platform: rotary_encoder
name: "Woonkamer 1 Rotary 1"
id: woonkamer1rotary1
pin_a: D6
pin_b: D7
filters:
- or:
- debounce: 0.1s
- delta: 10
on_value:
then:
- homeassistant.service:
service: light.turn_on
data_template:
entity_id: light.woonkamer_groep
brightness_pct: "{{ brightness_1 | int }}"
variables:
brightness_1: 'return id(woonkamer1rotary1).state * 4;'
It looks like Home Assistant can’t handle this on a (hue) group of 6 lights.
If I use this on a single light the result is fully acceptable, but on a group of 6 lights the result is that the lights dimm extremely slow. I can sometime take up till 5-10 seconds before the last service call actually reaches the lights. I am having the same problem when I handle the dimming in a home assistant automation like this:
- id: woonkamer_2_dimmer_1
alias: "woonkamer 2 dimmer 1"
trigger:
- platform: state
entity_id: sensor.woonkamer_2_dimmer_1
action:
service: light.turn_on
entity_id: light.woonkamer_groep
data_template:
brightness_pct: '{{states.sensor.woonkamer_2_dimmer_1.state | int*4}}'
Is there something I could try to optimize this?

Thanks for posting this! I got it working with a group of two lights like so:
sensor:
- platform: rotary_encoder
name: "Rotary Encoder"
id: bedroom_brightness
pin_a: D5
pin_b: D6
pin_reset: D7
filters:

- debounce: 0.1s

data_template:
entity_id: group.my_bedroom_lights_group
brightness_pct: "{{ brightness_1 | int }}"
variables:
brightness_1: 'return id(bedroom_brightness).state * 4;'
There is some lag with both light strips - but it wasn’t too bad. Also, I noticed that every time the light is turned off (brightness = 0) and then turned on, the color/temperature/hue is reset back to white. Can you think of a way to retain the light color or is it a home assistant setting?
I’m going to play around for a bit and see what else I can change.
I’m interested in flashing the esp8266 lights with ESPHome and see if they communicate faster using the API instead of MQTT.
Also, have you figured out how to use the “reset” pin as a button when you “click” it?
- homeassistant.service:

data_template:
entity_id: group.my_bedroom_lights_group
brightness_pct: "{{ brightness_1 | int }}"

This part definitely stopped working for me after the update to 1.14 and I have been unable to get it working again with lambda as Otto suggested. I am no coder, so If anyone could help me out, it would be greatly appreciated.
I want to pass a value of 1 to 100 (percent) to the brightness_pct of a home assistant entity upon rotating the encoder.

thanks to a hint from Otto; this fixes the issue!
Hi, esphone rotary encoder sensor. I’m also using the rotary encoder to control the LED light of cold and warm color temperature and brightness adjustment recently. Can you share the complete profile you are currently using? Thank!

Thank you! Rotary Quantity 2?
Wow Its great
3 dimmer and multiple dimmer you great job.
thxs for your yaml
have a nice day.
Do you have the circuit diagram and components list with the dimmer module ? I am new to these and still struggling with components to use.
Component: https://esphome.io/components/sensor/rotary_encoder.html
I dont’t have a circuit diagram, but you have my config. You should be able to get all pins from there.
