I’m replying to this old Topic to clarify something.
I can now say with certainty that the OmTech Polar does in fact work with LightBurn Bridge.
The only real challenge is that due to Bridge requirement that the Ruida IP be on a different subnet than the wifi network that the default Polar IP of 192.168.1.100 may conflict by being on the same network.
This can be remedied by changing the wifi subnet or by changing the IP of the Polar. The external control panel is required to change the IP address of the Polar.
This also means that the description in the Bridge ordering page is somewhat inaccurate.
I did not test this on an Onyx but it’s likely to work the same way. Gweike Cloud is more uncertain since they use a different board type.
