10 Favorite DIY IoT Projects using the esp8266

So many good uses for these chips, here are a few I have bookmarked for later projects.

  1. ESP Easy – by far the easiest way to connect a bunch of cheap sensors to an esp8266. I have about 6 of these doing various things.
  2. Bed Occupancy Sensor – FSR sensor for pressure and a simple automation to determine bed occupancy
  3. WiFi Candle Using multiple WS2812 addressable LEDs to create a simple lamp that flickers like a candle.
  4. Notification Flag – Raise a flag based on a simple condition. Would be nice to combine in tandem with…
  5. Mailbox Sensor – Notify when mailbox is opened.
  6. DIY Milight Hub – I’ve been using this and it works great. Control as many cheap Chinese RGB bulbs as you want.
  7. Simple Water Alarm – If water shorts the wires, it wakes a sleeping esp8266 and sounds the alarm
  8. Door/Window Monitor – Along the same lines, a simple magnetic switch monitors the status of a window or door.
  9. Smart Power Strip – Retrofitting a power strip with 2 banks of controllable outlets, using 3D printed parts.
  10. Weather Station Display – Another super cool 3D printed project that plugs in and displays info on a small screen.

Home Assistant Config: SF Ferry Sensor with Public Transit GTFS

I love the ferry. What I like most is how quiet it is. While all the morning commuters angrily inch across the gridlock of the Bay Bridge above, or packed trains screech below the water, you glide quietly through the fog towards the hills of the city. And on the afternoon commutes, they serve beer. Hard to beat.

I don’t have a regular work schedule, and Google Maps does not include ferry info, so taking one in the morning requires a little planning. What would make taking the ferry easier is if Home Assistant could look up the times for me.
