    • RE: What did you build today (Pictures) ?

      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

    • RE: Arduino Pro Mini & DS18B20

      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

    • RE: What did you build today (Pictures) ?

      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...

    • RE: Your workshop :)

      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

    • RE: Discount on Z-wave, clas ohlson

      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 🙂

    • RE: 💬 Heatpump / airconditioner controller

      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 🙂

    • Meet in Malmö, Summer 2016?

      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

    • RE: Improvement Xiaomi smart kettle (I need help!)

      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

    • RE: What's the "best" UPS for a Raspberry Pi 3B?

      I'm quite lazy, and use this approach and use a USB powerbank, and check if DHCP server is alive or dead (Dead= no 230V)

      RSPRO itx printer
      It looks like it's a private label name, and the manufacturer is Kora3d, you need to talk to those people and if you can't get any further support, don't waste any more money on this and buy yourself an Iprusa and get support from all the people that owns such a device

    • RE: ArduinoShrink

      @skywatch
      I'm amazed that you made it work, which is good in your case
      But in most cases it might not work, and your MCU will crash RAM/stack and you will have troubles to understand what goes wrong.
      https://electronics.stackexchange.com/questions/146298/what-happens-when-microcontrollers-run-out-of-ram

      So to be on se the safe side for most people, then buy 328 as it from Mouser only cost 1,92€ and the 168 costs1,40€ for the cheapest variant of each, so for a hobbyist this price is nothing compared to the troubles you might have. Naturally if you have production and manufactures thousands devices this price different is extra money in your pocket

    • RE: ArduinoShrink

      I'm sure ATmega 168 have too little memory to be used for run the mysensors code... so don't buy a ATmega168

      ATMega 168
      Program Memory Size (KB) 16
      SRAM (B) 1,024
      Data EEPROM/HEF (bytes) 512

      ATMega 328
      Program Memory Size (KB) 32
      SRAM (B) 2,048
      Data EEPROM/HEF (bytes) 1024

      Inside Hearing aids, the PCB are "mainly" only flexible PCB as the PCB must bend and follow the mechanical shape, think this picture gives an idea
