Home Automation with Home Assistant and ESP8266, 3D Printing, and other Technology
I saw that AliExpress had tiny OLED displays for just a few bucks, so I decided to order a few and figured that I would find a use for them. I haven’t found a use for them yet, but I figured I should go ahead and document what I did.
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.
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:
This blog post builds on my last post about the Wemos D1 Mini Garage Door Controller.
Sending a notification via Home Assistant is a simple process, and it is mostly well documented. However, I had trouble finding a solution that repeatedly sends a notification about a device state until that state changes. In this case, I wanted something to notify me when my garage door is open for a while, and then continue sending me notifications every 30 minutes until it’s closed.
I decided I wanted to be able to control my garage door using my phone. After some research, I decided to use an ESP8266 based Wemos D1 Mini and Home Assistant.
Here are the parts that will be needed:
