Majordome VS shelly-homekit

Everything is built around MQTT messaging and I got several daemons picking, processing and submitting information. - https://github.com/destroyedlolo/Marcel is in charge of low level interface with my 1-wire network, get weather forecast, ISP figures ... Lua user script are doing simple processing and validate data if needed - https://github.com/destroyedlolo/Majordome is the root of the automation. Lua user scripts are launch based on received even and implement the automation. Initially, it was fully a Lua application, but separating the low level (C++) and user part (Lua) makes the code more easily manageable, and simply everything. - https://github.com/destroyedlolo/Selene is a framework helpers to Lua. Thanks to its pluggins, it add some capabilities to Lua to generate graphical or textual interface ... and much more like data management, multi-threading (real threading, not only co-routine that wasn't enough for such massive event driven dashboard).

For sure : my own home automation is made with Lua scripts around a C++ framework (Majordome - See MaMaison branch for the scripts I'm using).

My smarthousing is 100% MQTT event driven (+ some timers obviously) and I created Majordome for automation : it is configured using simple text files in which you can add Lua script for smarter decisions.

You could potentially use the requisite Shelly for your use case and install this firmware on it to expose it to HomeKit as a lock

As far as I know you can flash a software on the relays: https://github.com/mongoose-os-apps/shelly-homekit And make them homekit compatible. Here is the video: https://youtu.be/BZc-kp4dDRw Just make sure to use correct download for your device

Shelly Firmware

Shelly one flashed with HomeKit. So easy cheap and one of the most reliable HomeKit devices I have. Watch the video https://github.com/mongoose-os-apps/shelly-homekit

The relay itself doesn’t matter especially given the fact that it’ll be on/off only, so I’d recommend a Shelly Plus 1 flashed with firmware to get it into HomeKit incredibly easily. The contactor doesn’t need to be anything fancy, just needs to be rated appropriately for the load at hand!

I use Shelly relays flashed with firmware (I prefer it over Homebridge) and automations to do this. It keeps the „normal“ look of the lightswitches and won’t cut power to the bulbs. Plus you can configure the different modes for the lightswitches! Check out the link for edge/toggle/etc. 👍🏼

If your light switch is a 2 gang switch I’d recommend picking up a Shelly 2.5, a Shelly 1 Plus, or Plus 1PM for single switches and flashing them with this firmware.

Alternatively, a more cost efficient option could be LED strips of your choice paired with a Shelly RGBW2 flashed with firmware.

The only thing I could think of is using something like a Shelly Plus 1 in HomeKit (firmware/Homebridge paired to a strike of the appropriate voltage.
