IoT project links 2019

Internet is full of intetesting IoT projects built using Arduino, Raspberry Pi, ESP8266, ESP32, and many other hardware platforms. I will collect links to intetesting IoT projects to comments.

Feel free to post your best IoT project links to comments…

    Mike Szczys Takes Back Control of His Wemo Lightswitch with MQTT, Python and a Raspberry Pi
    Sick of the proprietary software, Szczys took an afternoon to build a more flexible alternative using open source software.

    Mike Szczys has published the code for a build which replaces the proprietary back-end of an Internet of Things (IoT) lighting control system with an open source alternative based on MQTT and Python running on a Raspberry Pi.

    Tinkerer Trammell Hudson has written a guide to replacing the stock firmware on IKEA’s TRÅDFRI smart LED lighting drivers with MicroPython — and in doing so unlocking finer-grained brightness control with the promise of more to come

    Trammell Hudson Brings MicroPython to IKEA’s TRÅDFRI LED Controller Range, Unlocks Fine-Grain PWM

    Unhappy with the TRÅDFRI’s lowest brightness and powered by healthy curiosity Hudson’s hack brings the platform’s first MicroPython support

    Tinkerer Trammell Hudson has written a guide to replacing the stock firmware on IKEA’s TRÅDFRI smart LED lighting drivers with MicroPython — and in doing so unlocking finer-grained brightness control with the promise of more to come.

    “The CPU board is a Silcon Labs EFR32 ‘Wireless Gecko.’ which has a reasonable 256 KiB of program flash, 32 KiB of SRAM, a very nice 16-bit PWM for smooth dimming, and a ZigBee radio. Ikea also thoughtfully wired the debug port on the 10W LED driver, although the FLOALT requires soldering directly to the board.”

    The modified firmware has other advantages, too. Being based on MicroPython, it’s extremely open to further modification or more complex control tasks; it also offers the promise of local-only operation, protecting the user’s privacy when compared to systems which constantly communicate with remote servers outside of the user’s control — though, Hudson notes, “the default IKEA firmware is better than most for this.”

    Embedding A Smart Switch In A Java Factory

    [Maurice Makaay] bought a smart plug to add this beautiful drip coffee machine to his Z-Wave setup, but it isn’t all that smart. Starting the brew remotely means making sure that both the machine’s power switch and the smart plug switch are on.

    The answer comes in the form of a Z-Wave switch that takes dual inputs and is small enough to fit inside the machine. After a lot of searching around for compatible, splash-proof parts, [Maurice] replaced the existing on/off rocker with a momentary rocker for making coffee manually.

    [Maurice] went about this mains appliance hack the right way — he used extra thick wires connected with lever nuts, and kept the machine’s equally beautiful spare parts and safety documentation by his side the whole time.

    WiFi Humidity Sensor Lasts a Year or More Between Charges

    This sensor unit consists of a Wemos D1 mini, a BME280, an XC6206 3.3V LDO, and a single 18650 cell — all housed inside a 3D-printed case.

    ESP8266 – 1+ Year 18650 battery lifetime

    The first few version did not last very long on their batteries (2xAA), around 1-3 months. So I spend some extra effort reducing average power consumption.

    It has now been more then a year ago that I placed the first two sensors.
