Interesting Project, is there some more documentation available especially in regards to the wattage of the resistors R14-R17 and why no SMD ones are used here rather than those beefy ones which look like 1/2W or more?
Thanks! I'm looking for a way to upload the FreeCad Files here, but so far the Website does not allow uploading of unknown file types (like *.Fcstd). Cheers!
And the real product pictures now:

Sorry for the solder bridge replacing the R20 inrush current limiting resistor..that's just temporary until I get the real component . And yes, the capacitor across the bulb is still needed but it's a very small one of 0.1uF/250Vac and it should fit near the light bulb on the ceiling (only one is needed if there are two light bulbs on the same circuit).
The aluminum foil wrapped around that sponge is to "extend" the capacitive sensor so that it reaches the front plate fake plastic button. The 3d printed clear plastic around it is to hold it in place and also to spread the small leds light.
Everything is custom made except for the front plastics.
Here's another one: https://patents.google.com/patent/US20170133938
He claims the startup power is just 100nW. For contrast, TI says their BQ255xx chip requires 15 uW. i.e. an entire order of magnitude more. Sounds too good to be true, doesn't it? Which leads me to wonder: just how well are patents vetted before they're granted? Might it still be granted even if the author never made a a circuit that performed anywhere near as well as the patent claims? Is anyone even checking?
By the way, on a different topic, this might interest you: https://www.mouser.com/ProductDetail/426-DFR0579 It's a $12.90, 30mmx30mm, fully assembled breakout for the SPV1050, configured as a boost converter.
@Mr_sensor said in Easy/Newbie PCB for MySensors:
Can I have the pcb in the first shed also working as an extender, so the second pcb will be able to send out topics to the gateway as well? What to add to my code to achieve that?
Hello,
you must program it to be a repeater. Of course it will need to have radio on all the time, so it cannot be battery-powered.
