That looks nice and to be honest, I have more confidence in such a design with those well-known Hi-link power supplies than the ones included in the Sonoff's.
How much amps can these triacs (I assume) handle?
And it looks like there is room for later versions with more switches.
I was thinking about these switches lately and I guess there is also a market for these with 2 or 3 tip switch inputs, but only 1 switching output, since you can add switches near the consumers and very often still want to switch via the domotica system and not directly switching something at the position where these are mounted.
Or perhaps have multiple switch inputs to switch the same. (lights on while presence detected + lights on continuously)
Main priority is safety!
I have several devices in my house including the rooms of my children (they like the Neopixel Candle – Color Fader function ).
We have built several line of defenses to keep the devices safe to operate, despite missing certifications.
I (and many others) have good experiences with HLK-PM01 and it also delivers a stable power output.
For Meek MP1, I have switches from THT triacs to SMD triacs, currently it’s equipped with the BT136S, that should be able to carry 4 Amps. I have conducted test and they operate well even on high loads. Despite the theoretical high switching power, I will rate them for max. 350 Watt.
I have a 2 touch and 3 touch version in operations also, these are equipped with 2 or 3 triacs.
I have also a variant with 1 touch button, with 3 triac outputs to control home ventilation units.
In my kitchen, I have a Meek MP2(bastard version for my own use), with one touch button with 2 triac outputs. The RWCL sensor is so accurate that we do not manually switch the kitchen lights anymore. The touch button is merely to switch our garden lights. So the Doppler switches the kitchen lights and the touch button operates the garden light.
The beauty of Meek is that it’s equipped with ESPEasy !
The user is able to decide how the device reacts on a specific input. And that’s all because of you, the developpers of ESPEasy !
Thank you for all the time, efforts and energy you put into this project !
TD-er, I will PM you my phone number, , I hope that we can meet so I can personally hand over a Meek MP1 to you, for testing purposes.
