Home Assistant integration how? about tuya-mqtt HOT 2 CLOSED

Unfortunately, using this project requires a basic understanding of MQTT and, to integrate it with Home Assistant, how Home Assistant and MQTT work together. This knowledge is best gained by reading the Home Assistant MQTT documentation. The builtin Tuya component in Home Assistant has nothing to do with MQTT, it's a native component that talks directly to a special Home Assistant API which frontends Tuya Cloud and makes it very easy to control Tuya devices. It generally works reasonably well, but has a few quirks such as very slow state updates and it does require all commands to go through Tuya cloud. There is also a custom Tuya component for Home Assistant available to control Tuya devices locally called localtuya. If you don't have a strong understanding of Home Assistant and MQTT and your use case is specifically with regard to Home Assistant, then the localtuya project may be easier for you to use and I highly recommend it.

This project is simply acts as a bridge between Tuya devices and MQTT. It does not replace anything in Home Assistant, it simply connects to an MQTT broker just like Home Assistant does. That's pretty much all MQTT is a broker which various clients connect to, these clients publish messages to the broker and can also subscribe to topics to receive messages they are interested in from other clients.

If you have configured Home Assistant and the MQTT broker then all you need to do is setup this project to connect to the same broker and configure your device types and, during script startup, it will send automatic MQTT discovery via MQTT that Home Assistant will receive and automatically use to setup the devices.

If you have a device that is not supported "out-of-box" with this script (something other than a simple on/off or dimmable switch/light, or RGBTW light), then you'll need to create a custom template and manually define the device in Home Assistant, but this should not be required for a light.

Great! This helped fill in the big part of this system that was missing for me. I hope my post will help someone else too.

I have this (tuya-mqtt) I think working after a a little tweaking of my devices file. My devices are now discovered by Home Assistant, and I can turn them on/off by issuing commands from HA's MQTT client. However as 'entities' they are showing as 'unavailable', which is a problem. I will continue to poke at it, and see if I can figure that out next.

EDIT: rebooted HA, all is well :-)
