So my target was to make a cheap small copy of the HUE led strip with a wireless connection to domoticz that can copy over the colors of a HUE bulb or other LED strip.
Since I want it wireless mysensor seemed the most easy and since I already have a few other mysensor nodes.
To keep it wireless I decided to use a ESP unit and not a normal arduino with radio, just because of the size.
I made a small PCB with:
- 3 transistor's BC337 for PWM output to the led strip up to 0.8A per color (~10W/color)
- DB18B20 (to measure temperature and detect overheating)
- 3.3V power supply
- reset button
- header for programming
- jumper for GPIO 0 to set the unit to programming mode
I use a CP2102 programmer to program the ESP unit with arduino IDE
and with a little 12V supply I can hook up any RGB LED strip
I have made 2 arduino scripts to control the LED's, one based on the fastled library and one just writing analog output values for the PWM signal
Only open now is to fade in and out when changing brightness, but the start of that is already in the script
the temperature sensor will detect if the unit overheats and will switch if off for 1 minute, if that happens 5 times the unit will go into deep sleep mode and you need to manually reset the unit
The fast led version I also tested with adafruit neopixels... only the small strips with 8 lixed LEDs flicker but the normal LED strip not so that seems not related to my control but to the LED's
In the fast led based arduino code for brightness adjustment I just manually set a percentage that matches on first sight

next to that I have 1 watchdog script that switches on ID 100 to the node and the node will reply with an off at that ID so the node can be reset if there is no communication
a user variable has to be creased to store the current HUE settings (String)
a dummy text utility has to be created to store the HSV or RGB and dimmer values for the mysensor node to request
The device script contains calculations from HSV to RGB and RGB hex, I tried different formats for fowarding the data to the mysensor node and just kept it in the script in case I might need it later for troubleshooting
