What is it?

It is a triac based channel channel one dimmer one on/off board with esp8266 and atmeg328p. The dimming is controlled via Uart(esp8266) and can also be controlled via an external Pot which is kind of a two way feature, same goes for the on/off channel. We call this concept as virtual two way which basically helps you control it through either your phone or a manual switch/pot

Why did you make it?

To control two appliance like light, fan, etc.

What makes it special?

Small form factor
PCB Dimension 84X39X18 mm(LXWXH)
100-230V AC to DC converter on board supply.
Virtual two way
One Duel colour led
6 Extra GPIOs (two are used for Virtual two way switch)
Can load custom code.
Open source code and app(code is also available for dual dimer but ships with one dimmer one on/off code)
Compatible with Arduino IDE
With ABS enclosure(Dimension 115X45X28mm (LXWXH)

Dimmer doesn't work well with LED dimmable bulbs

I love the form factor and size, but with two units and several different brands of led bulbs, all of them flickered. Am in the states and run off 120v - which according to the specs *shouldn't* be an issue (and probably isn't the issue), but all the instructions reference 230v, so I can't be certain.

Brands of LED bulbs I tried:
Cree, GE and Phillips (not their smart bulbs). Of all the dimmable LED bulbs, I've had the best results with the Phillips, but they all buzzed and flickered and turned off completely under level 20. Maybe v2 will fix the problem?

Thanks for the review .We have tried it with a triac dimmable driver and have got good results . In india it is 230V AC @ 50Hz .
Here is the video .

Probably some code fine tuning is required for 120V AC.
in this part of the code
