Zemismart KS-811 with OpenBK7231N/OpenBeken

Recently a friend bought some Zemismart wall switches and they have a BK7231N chip rather than an ESP8266. This outines the OpenBeken project and how it can be used in the switch in a similar way to Tasmota/ESPHome.

WB3S replacement for Home Automation devices

More and more home automation devices from China are coming with no ESP8266 module, especially the TUYA based ones. Some are coming with a WB3S (which is different to the TYWB3S), but this can easily be removed and replaced with a cheap ESP12F (or similar) module.

Used EV Payback (Part 2, Was it worth it?)

How much to you save buying a used EV, and is it worth it? How long is the payback? This is my actual calculations about four years later and close to 100kkms on the odometer of the 2014 Nissan Leaf I purchased. Cutting to the chase, it was a LOT better than my estimates, and I wish we’d bought two of them.

Unfortunately I had a couple of issues flashing them and keeping them stable so had to find a solution.

I have a low cost WH1080 USB Weather station, connected by USB to an intel NUC running docker (x86). These weather stations have a bug in that they occasionally lock up and stop sending data. I implemented an automated way to reset it.

Xiaomi 10T Pro Updating (2021)

This is the method I followed for my Xiaomi Mi 10T Pro to get from my previously installed AOSP ROM to a stock based ROM (I’ll change to a modified stock ROM later). It includes Root so a bunch of useful things can be installed. I had a nice AOSP ROM previous to this, but the camera was a stumbling block – the Xiaomi stock camera is so much better.

Viewsonic Touch Screen for Home Assistant Display

Use of a pretty old Viewsonic All-in-One computer as a home automation display. I picked a couple of these up for around NZ$40 each, however found the touch screen didn’t work out of the box as drivers were missing from Linux.

Home Automation of Rinnai Gas Heater

Our Rinnai heater is a wall mounted/flued gas fire. Current control is via a large LCD remote control that also acts as the temperature sensor, and thermostat. It has some auto timing capability via way of programming the remote, but it is a bit clunky and not intuitive. The goal was to enable a better PID control of the temperature, and switch off/on control (occupancy, remotely before arrival, voice control, better scheduling etc). This shows how I connected to it with Home Assistant.
