So about a week after my post about sending a repeating notification through Home Assistant, the developers created a new ‘Alert’ component that basically made my post obsolete. So I decided to switch over to the Alert component and add some extra features.
I’ve seen these games around, and I wanted to make my own. The object is simple. The metal wand has a loop with a long windy wire going through it, and the object is to get from one end of the wire to the other, without touching the wand to the wire. It automatically detects when the game is starting and when it ends, and records the last time and record time. It also displays this information on the OLED display and it buzzes when the wire is touched.
I have a sump pump in my basement that doesn’t run very often. I wanted to be able to get a notification when it did run and a notification in the event of a water leak, which might indicate that the pump isn’t functioning properly. Detecting water was relatively simple, but trying to figure out when the pump runs was a little more challenging. I looked into a vibration sensor since the pipes would vibrate very lightly when it came one, but the sensor just wasn’t sensitive enough. I also considered measuring the amount of sound, but I thought that might cause some false positives when the kids were in the basement playing.
What you need:
I discovered this Arduino library a few weeks ago, and was surprised to see that there aren’t more projects that make use of it. I feel that anyone that is using OTA would have a use for this library. So I decided to make a post because I’m thinking that there are many people that don’t know about it. This library was written by JoaoLopesF.
After installing my Garage Door Controller, I wanted my next project to be something cooler. Of course, there’s nothing cooler than a smart gas fireplace.
Here is a list of things you will need to get started:
- A gas fireplace. Read below to make sure your fireplace will work with this.
- Wemos D1 Mini | AliExpress
- MicroUSB Cable and Charger for Wemos
- 5V Relay | AliExpress
- Dupont jumpers | AliExpress
- Electronic Project Case (Optional)
Software that you will need:
- Home Assistant configured with an MQTT broker such as Mosquitto
- Arduino IDE | How to setup Arduino IDE with a Wemos D1 Mini
I created a gallery of all the images for this project in case anyone needs a closer look at any of the wiring.
