I have a Carrier Infinity HVAC system, which unfortunately can’t be managed via SmartThings. However, there is a HomeAssistant integration which uses Carrier’s cloud API to monitor and control the system.
I’ve got a HA instance running on a Raspberry Pi with the Carrier integration, as well as the SmartThings integration. I can see and control all my SmartThings devices via HA (which I won’t be doing - happy with SmartThings as my home automation system).
What I want to understand is how I can share the Carrier HomeAssistant devices with SmartThings, so I can manage my HVAC on SmartThings using HA as a bridge. All the searching I do seems to focus on folks wanting to do the opposite - ie control SmartThings devices via HA.
HomeAssistant has two Matter Bridge add-ons that you can check out: Home-Assistant-Matter-Hub and Matter Bridge Assistant. You can get more info on their community forum. Looks like I typed too slow… someone responded before me
well, i’m adventuring in integrating HA to smartthings via matter with Home-Assistant-Matter-Hub. It seemed to me to be the best choice, because it uses direct API integration with HA (no PATs or plugins).
My goal is to bring LG Air Conditioners from ThinQ to Smartthings, so:
configured the LG ThinQ integration with HA, my AC was brought to HA as a “Climate” entity with all the modes and commands: on/off, fan, cold, heat, dehumidification, fan speed control, oscillation control, …
I configured the Matter Hub addon, created a bridge, and commissioned it with SmartThings, and that was it; my LG AC appeared in SmartThings to be controlled.
One thing that bothers me is that the air conditioner is exported as a thermostat via matter to smartthings.
Is it possible to export an AC as an AC? Whose “fault” is it?
I use both MatterBridge and Matter Hub to bring Home Assistant devices into SmartThings. They both have there advantages and disadvantages.
MatterBridge - It will bring the entire device with multiple Entities into ST as a single device, while Matter Bridge will bring each Entity into SmartThings as separate devices. An example is my VOC sensors. MatterBridge gives you 1 ST device with temperature, humidity, VOC and battery. Matter Hub would require 3 separate devices in ST. Since I am near the 300 device limit this is a major consideration for me.
Matter Hub - It brings each Entity of multiple Entity devices into ST are separate devices. And you might want that. An example would be a power strip with 6 outlets, where you want individual ST devices for each outlet. Matter Hub also let’s you set up multiple matter hubs in HA. So if you have multiple ST hubs you can set up separate HA Matter Hubs, one for each ST hub to keep the matter devices local in ST routines.
Also some devices just work better with one method but not the other. So that might force you to one or the other for that device.
If you try MatterBridge make sure you set it up so that it only selects devices that you have “Labeled”. If you don’t it will try to make every device in HA (could be hundreds) part of the Matter device import. This will cause it to fail due to the large amount of devices and it will mess things up.
So my advice is to try both and see what works best for you.
The problem in this case is with the SmartThings driver. I tested it with LG air devices exported via Home Assistant and also with Zigbee IR devices. And in both cases, it appears this way.
