  • Trying to detect falling edge on input where also a pulse counter sensor is connected
    1 project | | 11 May 2022
    If your output requirement needs the tighter timing, you'll probably need to make a modified copy of the pulse counter component (here), use that instead, and insert your output behaviour in the pulse interrupt near the top of pulse_counter_sensor.cpp.
  • Has anyone successfully added a Wemos C3 Mini?
    1 project | | 2 May 2022
    esphome has an output_power setting in the wifi component, but it doesn’t allow setting it that low. I found a PR from two weeks ago that says it fixes that issue, but 🤷‍♂️ if it’ll be merged or when it’d be released:
  • Taking a run at HA for my Insteon systems.
    3 projects | | 2 May 2022
    I have an Insteon IOLinc controlling my garage door with a magnetic sensor similar to this. It works just fine. However, I'm in the process of planning to replace the IOLinc with an esphome sensor that has a motion sensor, car sensors, and a laser break sensor for parking. If you want to fall down the rabbit hole, learn how to do esphome. I've got it doing a number of tasks around the house that are wholly impossible with Insteon.
  • ESPHome and FastLED on Home Assistant
    2 projects | | 25 Apr 2022
    Maybe fastled_lambda has been deprecated or something. This example is from 4 or so years ago, and the comment you linked says its running on an older version. Maybe I'll look at the version history to see if this word has been renamed.

  • The end of Insteon and why the smart home keeps faltering – Stacey on IoT

    If you're up for some light soldering, I'd recommend picking up a few Sonoff Basics and/or wall plugs and then flashing them with ESPHome ( These devices are simple and cheap ($5-6 each), basically just an ESP8266 chip connected to a relay, a button, and a status LED. You have to solder to attach four pins to the board so you can flash it, then you can close it up forever. Future updates happen over-the-air.

    I am far from being an electrical engineer, and found that these guides, plus a few YouTube videos, got me to the point where this feels routine. I now have over a dozen in my house, controlling all manner of things.

    I've also had fun installing temperature and humidity sensors to Wemos D1 Minis ($2-$3, basically just an ESP8266 chip on a development board) to monitor climate around the house. During the winter, houseplants really like to have higher humidity... we bought a bunch of dumb humidifiers at goodwill, installed Sonos Basic relays inside them, and set rules for them to turn on when the humidity in the room drops too low.

  • Help! I have too much lettuce now!

    The probes are from Atlas Scientific’s EZO series. They communicate to an ESP32 via i2c. It’s all set up to talk to HomeAssistant through ESPHome
  • Migrating code from Raspberry Pi to Wemos D1 Mini
    2 projects | | 24 Mar 2022
    As others have said I would recommend starting with an ESP8266 or ESP32 board. There are Arduino compatible libraries out there already that you could couple with PlatformIO or ESPHome to have the microcontroller talk directly to Firebase.
  • Need better device to control electric gate *easily*
    1 project | | 24 Mar 2022
    If it were me I'd use ESPHome. You can write your own code and flash your own sensor. By "write your own code" it's really just writing some settings in a configuration file. For something as simple as this, it would be very minimal.
  • We have built open modular hardware for home automation. ESPHome ready. Asking for feedback
    2 projects | | 15 Mar 2022
    It could work as PLC. The main feature it will be opensource and it is based on opensource technology (EspHome for firmware, HomeAssistant for as a home automation software). The main use-cases are listed on the website and are similar to Loxone - controlling wall-switches, reading sensors, driving LED (both addressable and analog), driving relays and other load, reading data from smart meters, etc.
