ESPHome on dingtian-tech relay modules

Fri, 21 Apr 2023 00:00:00 +0000

This is another one of those quick “I wish that was easier to find when I was googling it” posts.

For a project, I needed a small relay module to switch a few mains loads. I chose this generic looking relay module from AliExpress because it was powered by an ESP32 and featured ethernet connectivity.

AliExpress is full of generic looking relay modules but this one is branded dingtian-tech

Teardown and Home Assistant integration with two generic Chinese 'smart' power strips.

I love the Sonoff-S31 smart plugs. They’re cheap, well made and - most importantly - trivial to flash with ESPHome and integrate into Home Assistant. They do have one obvious draw back, though; optimized for a “traditional” US style outlet. When you try to deploy them to a power strip, you end up loosing about 50% of the outlets on the strip!

This is how you loose about 50% of the outlets on your power strip.

Installing Tasmota on the Xiaomi Desk Lamp

MJGJD02YL vs MUGJD01YL

There are at least two versions of this lamp. Thanks to @htvekov for confirming that the MUGJD01YL variant does not contain an ESP32. It contains a TLSR8368. Some photos of the MUGJD01YL internals are provided below.

If you’re here just for “how do I flash tasmota” bit, skip to the Tasmota section below.

Now with ESPHome

ESPHome support for the single-core ESP32 chip in the lamp has come a long way. You can find the ESPHome configuration that I used with this lamp below.

I was looking for a way to light my desk my desk without screen glare. The easiest way to prevent glare on a screen is to change the orientation of the light relative to the screen either from under or behind the screen. This is not practical for ceiling mounted lights or for any floor lamps.

Fixing Home Assistant discovery with Tasmota on the Treatlife DS03

Update

This post is now deprecated. It has been superseded by Using ESPHome with the Treatlife DS03 from 2022-06.

UPDATE: (2021-10-22): Tasmota 9.5.0 has been superseded by the new Tasmota 10.0.0 release. This release works perfectly with the rules/automation outlined below; you no longer need to avoid the problematic 9.5 release with the DS03. I am extremely grateful to every one of the people that contributes to the Tasmota project to keep it improving!

Two Tasmota rules

Fri, 20 Nov 2020 00:00:00 +0000

Tasmota is an incredibly powerful alternative/open source firmware for the ever popular Espressif family of WiFi equipped microcontrollers. This does not need to be another post espousing it’s many awesome qualities, so just trust me on this; Tasmota is AWESOME.

Tasmota supports user configurable rules which are simple commands wired into various device triggers. In short; a device running Tasmota gains some autonomy to react to events without needing to report the event to, and wait for commands from, a remote server.
