    I have been looking for a product like this for a long time !
    can they deliver the PCB to Germany?

    This is really good and I have been looking for a similar solution for a while now.

    I have a couple of suggestions for the V2.0:

    – An Ethernet port option for a wired connection to the server (may be something similar to “Lan8720 breakout”). Perhaps using a Board that supports PoE ?

    – PIR sensor integration because why not!

    – a binary_sensor ( a press button switch) to toggel the LED light locally using “Template Switch” function incase the connection with Home-Assistant server was lost for some reason

      For general purpose, there are four gpio pins exposed, together with a power connection and ground. Check the top header on the PCB. Unfortunately there was no physical space to add screw terminals for these connections.
      We will keep the suggestion of the Ethernet port / POE in mind. Maybe we’ll implement it in a future design.

    Couldn’t find an analog 5 channel? What about the H801? https://esphome.io/cookbook/h801.html

      That is indeed a 5 channel controller. I had 2 of them in my house, but it is esp8266 based and thus has software PWM with frequencies up to ‘only’ 1000Hz. The esp32 does hardware PWM up to 40Mhz.
      I have mine running at 25.000Hz which makes a huge difference for video. If I now film from my office or make a teams call, there is no more flickering.
      I also have the esp32 BLE enabled so when I am in the office some motion based automations are disabled using BLE presence detection.

      The H801 also has no options for external sensors and no options for converting a analog channel to digital (addressable led).

    […] previous design, the ET-AL01 Analog LED controller, was designed to control the regular “Analog” (RGB) LED strips. […]
