@HouseIOT Sorry to trouble you, i use a mysensors-wifi-gateway with protocol 2.1.1 , and my homeautomation is home-assistant. I can't use your dimmer in my system.

After read the reference, there need to add V-percentage and V-status in the code, as a newbie , I can't do it myself. So I wondered，can you do me a favor?

Thanks a lot.

@HouseIOT
I replaced the led1 with a 0Ω resistor, YEAH! Works!:laughing:

and I will replace the led 2,3,4

@HouseIOT The voltage output from the AMS1117-3.3 is 3.29v, and the voltage of the JP1 (VCC & GND) is 3.29v.

And when the V_PERCENTAGE is 100, the voltage input of the pin1&2 with OK2(3,4,5) is 0.825V.

when V_PERCENTAGE is 30, the voltage input of the pin1&2 with OK2(3,4,5) is 0.25V.

except the voltage input of OK(2,3,4,5) is definitely low，others seems OK.

@HouseIOT Hi，in your schematics, the D1 is a DIODE, but in your BOM, D1 is nothing. Maybe the problem is here?

@HouseIOT supply voltage is 220v.

@HouseIOT THANKS for rapid reply！

I changed the resistor(r5) to 0 as pitcture shown, no function...

@HouseIOT As a newbie, I did a board completely following you schematics. But unfortunately，not working...

I use the MYsensores-bootloader(8Mhz，V1.5.4!), and I flashed your source ino-code into the board.

I can see the dimmer in the MYSController(as picture show), but there's no output from the X1.

My gateway is a esp8266 wifi gateway, version is 2.1.1 and it works fine.

PS: After testing job, the circuits of low voltage seems work well, shortcuts x5 and x2, the indicator led show lightness change(OFF, 30 & 100). The problem maybe in the Hi-voltage parts.

PLS help, THANKS a lot !

@HouseIOT There's missing a hole of C17

Awesome works！ Really want to have one！THX！

That's my fool. I saw it in the develop branch.

@tonnerre33 I just browsed your Github repo, found nothing there today, you deleted the contents？
