The process: 1. 3D Printing 3D model: https://www.printables.com/model/23859 Slicing: I used the following settings, as recommended by the model designer: I’ve tried to…

Proxmox server temperature tracking in Home Assistant
(Link to the original blog post with a proper layout) It’s a pity that #Proxmox doesn’t report CPU and other temperatures to #homeassistant. I had several freezes of my old laptop that runs Proxmox due to a stuck CPU fan. I googled a bit and found an elegant solution for temperature reporting: a command_line sensor.…

3D printing with TPU
(original post with nicer layout here) #TPU material is one of my favourite materials for #3Dprinting. During the last year I’ve printed some usable objects for home improvement. Why? Material I’m using Overture’s orange TPU. Settings I’m printing with the following settings: Practical cases: 1. Gaskets A rubber gasket for my garden hose connector broke.…

3Dprinting drainage pipe connector
#3Dprinting drainage pipe connector What’s #3dprinting printing today? Oh, nothing special, just a simple drainage pipe connector. The plastic pipe connecting the gutter and rainwater container broke some time ago and I attached it with duct tape. It looked gross and I decided to make a pretty female-female connector. #TinkerCAD: See these little teeth inside…

How I killed e-ink display
TL:DR: I don’t know how, but it no longer works. In the previous post, I shared the joy of making #ESP32 #Lilygo T5 2.13′ e-ink display finally work and show some sensor data from #homeassistant. The joy lasted only a week. Yesterday I decided I’d print a nice case for it. I found a great…

How to make Fire HD tablet talk in Home Assistant
If you have Amazon’s #FireHD (or any other #Android) tablet that shows your #homeassistant dashboard, you can make it talk. I created a new automation (triggered by a motion sensor) which greets me when I approach the tablet: I used the ‘Send notification’ action, chose the tablet and inserted ‘TTS‘ in the message field. Then…

Home Assistant and nice statistics graphs
One of the things that bothered me in #homeassistant for more than a year was the following: I couldn’t figure out why some entities/sensors can draw nice longterm statistics graphs like this (with average, max, min values): and some show only bulky history charts (10 days of data) like this: #til Today I learned I…

Fixing junk LED light found on the street
I have a nasty habit of picking up bolts, nuts and other ‘trash’ lying on the ground. A few days ago, I was walking on the road (which also leads to a local waste collection centre) and found a drywall LED spotlight. It looks like it fell from somebody’s trailer. I picked it up, maybe…

Dishwasher saga part 3 (it wasn’t a microswitch!)
As I wrote in my previous post I was so happy when I finally discovered what’s wrong with my 20yr old #Bosch #dishwasher. A faulty microswitch. Except that it wasn’t. The joy was over after a day and the symptoms returned: I disassembled the dishwasher for the 23rd time. Added a bolt to a microswitch…
