I changed my home switchs to Livolo 3 years ago... and now, I am interesting in connect it with Alexa by Wifi. Are there any project, adapter, accesory or similar to integrate it?
I have got the accelerometer (MPU6050) working as a service in nordic mbed, and I thought I would throw in some of what I learned to add to the great work you have done.
@skywatch great, thanks a lot for your suggestion. A bit of research on the internet educated me about these diodes looks like they already exist on the board that carries the relay. However, i deeply thank you for the info. This forum and internet in general is such a powerful tool
@ejlane your concern is fully justified i also come from an engineering background and i like to think "worse case scenario".
The more one look the more one find that the very vast majority or microwave ovens work the same way : there are 3 industrial switches built in the door lock. 2 of them are cabled on the "power side", one is for signaling ("software side"). So we are pretty safe on that matter.
But you are so right about safety. Magnetron do emitt dangerous waves and capacitors and stuff packed in the oven can be deadly because of high voltage.
Thanks both for suggestions. I will come back with updated sketches and beg for advice once more

I finally got it to work. Look at my post on the Home Assistant forum.
There is an amazing thing that someone in the MySensors world did that makes RPi I/O very easy! Just like the Arduino, one uses the code:
pinMode(MphysicalPin, OUTPUT);
I couldn't believe my eyes when I saw that. And then got double flabbergasted when I discovered that pin is the physical pin of the RPi! No mapping of GPIOi to the pins.
Whew!
So the I/O was easier than both of us could have imagined! @mfalkvidd if you know who did this, send them praise and thanks.

I would like to step up 3.3V from my power supply with the help of a dc-dc-boost converter to 5V and then I want to draw 500mA by placing a 10 Ohm resistor between the output-pin of the boost-converter and ground.
I just tested 2 led types with no flicker on my attiny circuit.
It is funny, the expensive leds like from philips: Dimmable 3.8W Warm White have a flickering behavior .
A cheap one available in Action from LSC 6.3W, Dim to Warm and 460 Lumen has no flickering behavior.
Another one from Osram Par 1650: 5.5W Dimmable Warm White, 350 Lumen also has no flickering.
The philips has the best Energy savings though : 4kWh compared to 7kWh for the LSC one.
Is there a relation between energy savings and dim quality ?
