Updated FilaWeigher Filament Scale – Now with Temperature, Humidity, Pressure, and MQTT

FacebooktwitterredditpinterestlinkedinmailFacebooktwitterredditpinterestlinkedinmail

As I talked about in my last post about the FilaWeigher, I wanted to add MQTT and temperature/humidity(Using the BME280) to that project. Well, I've done that. Refer to the previous post for more details. But now for this one, I'm just going to focus on the updated code and schematics, and the Home Assistant integration via MQTT. I'm going to leave the old post up for the people that don't want MQTT or the BME280 sensor. This version also has JSON output of all the sensors which allows for OctoPrint integration(I actually just finished up that plugin and I'm going to be posting that up soon).

I created this project so I can know exactly how much filament is left on a spool for my 3D printer, an Ender 5 I wrote about previously. However, it can very well be used to weigh anything else. I put a few settings that are specific to the filament, but they don't have to be used.

Recently, Amazon was selling the refurbished Fire 7 tablet for less than $40. The new one runs for juts $10 more. So I figured I would order it and see if it would be an option. After spending an hour with it, I felt confident that I can make it work. I’ve been running it for a couple weeks at the time of writing, and it’s been awesome.

Using the Xiaomi Aqara buttons with Home Assistant via Zigbee2MQTT

I had recently put Sengled Zigbee bulbs in my nightstand lamps to pair with Zigbee2MQTT on Home Assistant. I was using them to automatically turn the lights off/on when playing/pausing a movie on the TV. However, we found ourselves cutting power to the night stand to turn them off since pulling out our phone to turn them off was too much of a hassle. So when they had no power, the automation for those bulbs wouldn't work unless I manually turned them back on. Not an ideal situation.

This is an update to my post about the Garage Door Notification which was based on my Wifi Garage Door Controller .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.
