Multiple PCs integrated into Home Assistant (Add a second host in the integration config)

[LeoLTM]

I want to integrate my two machines running OpenRGB into Home Assistant. The setup of the first one worked perfect (Installed OpenRGB, started server, installed HACS Integration, added in integrations section, entered IP of the first desktop), but I was not able to find a way to add a second desktop with a different IP address to the openRGB integration.

Same issue here. Would like to add more than only one PC.

I get this "aborted" error when trying to add a 2nd PC. I guess the integration is not set up to handle multiple instances?

[LeoLTM]

Yeah, sadly there is no way to connect a 2nd or 3rd machine yet... Would be very useful!

Agreed. Have multiple PCs in a single room and would love to be able to control the colours at the same time.

If not multiple PCs but multiple IPs, I guess loosely multiple PCs, would be fantastic! I sometimes forget to plug my ethernet cable back into my main PC and would love to add both IP addresses for my WiFi MAC and Ethernet MAC to ensure I am always able to control my lights. I use this extension with Lumia Streams integration of Home Assistant to help add effects for things when I stream. Other than this no issue at all!

Thanks for taking care of this, @koying! Unfortunately I've encountered a minor bug with this. When adding a second instance of the integration, it finds the new devices from the new computer, but also the devices found from the first instance.

For example, if the first instance has 4 devices, and the second instance has 3, upon adding the second computer, 7 devices are reported as being added.

The devices for the first computer are now tied to both instances of the integration (see last four devices in the screenshot below):

Been experimenting with this a bit more. When a second device is added, the entities from the first device are sometimes allocated to the second device, and the ones for the second device are lost.

I've been poking around in config_entities, device_registry and entity_registry and when additional devices are added, the links between the entities -> devices become mismatched.

What might be relevant: I have two identical computers that I'm adding, so the devices will share the same model numbers etc.

I have removed both instances, added one, then set logging level for the component to debug then added a second instance. The following appeared in the log:

The devices that share the same name will reappear as ERRORs in the log every ~20 seconds after the initial view. It appears that the component is attempting to add the entities using their model names name. One of my computers has a different GPU which can be added without issue (light.asus_rog_strix_rtx_2070s_a8g_gaming_8g_0).

Latest release (2.2) resolves this. Thank you!
