Shelly Plus RGBW PM | WiFi Smart Remote Control for RGBW Led Strips with Power Metering | Home Automation | Bluetooth Gateway | No Hub | Compatible with Alexa & Google Home | iOS Android App

Shelly devices including these RGBW controllers just simply work great and the way people want them to!No app needed, so subscription, no entering my contact info, simple effective, and solid. Most of the rest of IOT devices need to learn from Shelly.

Compact size. Extraordinary breadth of settings and features available on the app. Works well with home assistant. Overall has been reliable.

Shelly ecosystem is pretty strong for IOT, in my limited option. This device was excellent for turning a Low Voltage dumb Light Switch into a Homekit enabled endpoint. See attached photo for setup with:- Input: (1) 24V DC power via positive (red) and negative (white)- Output: (3) 24V LED strips- Switch: Single Pole, Leviton/Brand doesn't matter- Smart controller: Shelly Plus RGBW PMSetting the device profile to "Lights x4" and Input 1 (I1) to Toggle the smart controls work as well as physical switch going "ON". Setting Input 1 to Edge mode acts like a pure toggle -- physical switch goes between on/off regardless of position.Homekit firmware is available on Github, flashing it is pretty easy. Reverting was easily done via web interface. Shelly native app is quite excellent and highlights just how much you can do with the Shelly devices (scripts, automations, toggles, IOT galore). Felt like a well produced product.

Most RGBW controllers use the ESP8266, but it only has software PWM, which inherently flickers and can't get to high enough frequencies to prevent visible pulsing and camera artifacts. These modules solve that by using ESP32 chips instead, which bestows high speed hardware PWM on all of the outputs.The stock firmware is surprisingly functional, with the main missing feature for me being no support for 2xCCT. If you're crafty enough, you can flash the module with ESPhome or Tasmota, but as of Nov 2024, it's very difficult to do OTA, so you'll have to figure out a way to connect to the non-standard programming pins on the bottom of the unit.

The price of these are amazing. I typically like using Zwave or Zigbee for co trolling lights but these have been exceptionally stable and have periodic OTA updates. I would definitely buy again.

Why did you pick this product vs others?:Shelly products are easy to setup and add to Home Assistant.

Documentation could be better, but Google is your friend here. Once I figured it out, it has been a fantastic addition to my 12vDC environment. RV and off-grid uses jump to mind with the easy wifi control.

Shelly builds great products, this one arrived already assigned to another user account and Shelly support was great at resolving the issue!
