Wireless dimming between Shelly Plus I4 and Shelly Dimmer 2 / Pro Dimmer
In this guide, we describe how to control a Shelly Dimmer 2 wireless from a Shelly Plus I4 input module.
We will be working from the web interface of the Shelly devices.
We will use a script to emulate the dimming functionality. When the script is set up, you get the following functionality:
- Single push: on/off
- Double short push: 100 % light
- Long push: Brightness up/down
Step 1: Access the device's web interface
Step 2: update firmware
Step 3: Set input mode to "button".
Step 4: Insert and prepare script
Turn on Websocket debug
Insert script
Now copy the entire code below into the new script.

For the Pro dimmer there are two scripts.
One for controlling Channel 1 and another for Channel 2

Step 5a: Configure script (1 Channel)
Find and change IP address
When the script is pasted, navigate to lines 12-15.
There are four lines containing IP addresses. Each line/IP address corresponds to an input on the Shelly I4.
If you want the first input (0) on the I4 to control a Dimmer 2 with the IP address 192.168.1.34, you need to modify the IP in the first line to match.
If you also want input 2 (1) to operate another Dimmer 2, remove the double slashes // and update that line with the IP address of the corresponding Dimmer 2. Repeat this process for the remaining inputs.
Before
let dimmer = [
'192.168.61.240', // dimmer controlled with button 0
// '192.168.61.241', // dimmer controlled with button 1
// '192.168.61.242', // dimmer controlled with button 2
// '192.168.61.243', // dimmer controlled with button 3
After
let dimmer = [
'192.168.1.34', // dimmer controlled with button 0
'192.168.1.57', // dimmer controlled with button 1
// '192.168.61.242', // dimmer controlled with button 2
// '192.168.61.243', // dimmer controlled with button 3
Step 5b: Configure script (2 channel Pro Dimmer)
Example when we want to control both Ch.1 and Ch.2 from input 0 and 1 on the same device
Enter a fictional IP address on the first line; otherwise, the script won’t recognize input from input 1.
Script for controlling Ch.1
let dimmer = [
'192.168.61.240', // dimmer controlled with button 0
// '192.168.61.241', // dimmer controlled with button 1
// '192.168.61.242', // dimmer controlled with button 2
// '192.168.61.243', // dimmer controlled with button 3
Script for controlling Ch.2
let dimmer = [
'0.0.0.0', // dimmer controlled with button 0
'192.168.61.240', // dimmer controlled with button 1
// '192.168.61.242', // dimmer controlled with button 2
// '192.168.61.243', // dimmer controlled with button 3
