Here’s another one of my notes about DIY smart home solutions. This time I decided to find a better replacement for Aqara temperature/humidity sensors using a devboard with a esp8266+stm8 (esp-14s module) and a homebrew esphome-based firmware. With aqara’s stock sensors I didn’t like their crappy precision and no way to change the sensor polling time. So, why not get almost all of those wishes fulfilled with a ready-made esp8266 module? Besides, nearly no price difference. Well, that’s what this post is about.Continue reading “Trying alternatives for Aqara temperature sensors”
At the first glance, it’s a very easy task. However it has a number of less obvious pitfalls when you’re working with microcontrollers via some kind of gdb stub or openocd and the memory you’re actually uploading your .bin file is the flash memory of an MCU (e.g. stm32). I decided to gather the common pitfalls in a single blog post.Continue reading “Note to self: How to flash .bin files via “raw” gdb”
This is my second note about Xiaomi Aqara smart home stuff. Something tells me it’s not the last one. In this note I’ll tell about implementing home automation that will reliably work offline using readily available hardware from Xiaomi and (at the same time) keeping your privacy intact. After all, not everyone is ready to share all the private stuff with some corporate crooks 😉Continue reading “How to use Xiaomi Aqara and keep you privacy”
There are some pretty good smart light switches called Xiaomi Aqara. It’s basically a light switch with a relay and Zigbee wireless interface inside. They are integrated with Xiaomi zigbee gateway and can be remotely controlled. Zigbee gateway uses them as a proxy in case the battery-powered sensor is not in the direct range. This post will be about adding a better wall-mount box for those little things.
Another year, another version of the led-o-blinker. This time I had to go wired to fit into the 40 minute deadline. Happy holidays!
I use LineageOS and Magisk root (A magic tool that help Android Pay and root access coexist). With Lineage you can receive updates every week on monday (for my Oneplus 5T) and so far they’ve been really stable. All was good until the last update of may bricked my cellphone. As it turned out Lineage build was perfectly fine, the bug was with Magisk (Once I removed it and flashed the update – everything worked, except for Magisk). In this blog post I’ll tell about Magisk’s epic fail, and will provide a link to fixed Magisk version that doesn’t turn your phone into a
I recently got myself a OnePlus 5t cell phone. (Mostly because it’s fully supported by LineageOS which is IMO the best option you can get for your phone). Finally I got a few spare moments to design a nice 3-printed phone stand for it.
Okay, starting from right now my blog should be available via ipv6 as well.
This post covers my music player with web interface that I’ve added to my workshop (or, perhaps, I’d better call it “my lab”?) In this post I will walk through the messy details of making such a box and document all the tricky bits.
