Bathroom controller. It consist of a relaybox with a HLK 5v power source, it's hidden in the closet. Then I have realy to light, nightlight, mirrorheat, and extraction fan
And then the controller it self it's a Wemos D1 Mini Pro, Si7021 Temp/Hum, sensor and a PIR HC-SR501
3D file is created with Freecad, STL files are available here:

As I have updated my workshop, so I no longer sit at my family kitchen table, but instead have a man-cave, behind a sliding-door closet, next to the water-heater
when compiling in Arduino IDEdo you remember to select correct Arduino board, Pro Mini and choose 3.3v 8MHz.
Tools->Board->"Arduino Pro or Pro Mini"
Tools->Board->Processor->3,3V 8MHz
Maybe if you forget this you will compile with wrong oscillator frequency and get wrong timings to your communication to DS18B20
Maybe a bit off-topic, but I use octoprint as server for my 3d printer, and use Domoticz as homeautomation server. I want to know when 3D print is done, so I created a node-red flow that connects this via MQTT, so domotics shows print progress...

Thank you Flopp
Now my wife will be a happy wife - since I will upgrade my ceiling lamp to be dimmable and she will have a happy husband since I can remote control the lamp when she forgets to switch it off - I think this is a win-win situation 
I copied ToniA's approach to get 5V from the Heatpump, and soldered wires to the IR detection circuit:

We were thinking of releasing 2.0 when we were having the MySensors meetup/BBQ at my house 9th of July.
So using the term "release-party" is also valid here
Hi I was thinking if we should meet in Malmö (Sweden) for a 1 day afternoon BBQ and nerdy discussion about MySensor stuff?
I can invite for using our garden and the grill
either purchase a standard cheap kettle, and a wallplug, then you can switch on/off via this. Or else you need to create a device that can emulate a persons capacity touching
This guy used a floating pin on Arduino, and then set it to GND, maybe worth a try...

Why?
the chip isn't cheap -and as I remember you MUST be a participating member of the Z-wave alliance were minimum fee us US$ 3000 per year
The technique with a large GND-plane can be quite well used when dealing with RF circuitry
But I agree this isn't pretty looking electronics...
@Joe
Sorry no idea where to get an Utrusta power supply
I think this is the most difficult part in the whole tasks in our household...
The kids will soon learn to leave the dirty laundry somewhere else, so the baskets are empty and there are internet (tryk avler modtryk).
I somehow think old-fashioned dog/punishment training are working - what will happen if the don't get their clothes laundered and it's left dirty?!?
Now being serious, can you do something with a strain-gauge, so you can measure the weight of the basket, if it's placed inside the cabinet on a shelf? then you can to improve WAF add a "false" shelf, that the loadcell/ strain-gauge is lying below, so that it actually are hidden
Help to understand strain gauge and load cells:

Will your share the schematic files? or a picture of it?

iron and toner transfer, then etched and soldered and finally acrylic spray on cobber so it won't corrode
wifi uses a lot of handshaking for communication = drain batteries too fast
Mysensors and other "good" protocols have a little handshake and preserves battery energi
I am only using wifi devices that are mains/230V powered
Why not purchase a Raspberry Pie and a SD card + casing , then you have a server?
@noclue said in Sensor advice:
@hj_sk I want to control my idea. I have put my ideas out there before, only to be stolen.
either do as Tbowmo suggests, or if you are afraid that we will all steal your idea, I can recommend to contact a electronic development company, that will sign a non-disclosure contract, a company could be this one (I'm not affiliated with the specific company)

Typically wifi consumes considerable energy for handshake so use wifi on battery isn't the greatest idea. but using it with mains power is quite good
If you want to use battery operated devices, you must use a better protocol than wifi
