Hello, I’m still working on this one.
I rang polyaire and so far they’ve been pretty helpful.
They have a tcp port open which they aren’t willing to release information about to the public. I believe it was port 8899 or something. I can connect to it like any other com port and it spits out information every now and then. However, I don’t know how to control the aircon from this.
The polyaire also comes with a 2 wire rs485 port on the controller which can be connected to using mod bus. Polyaire have given me access to the mod bus commands but I’m not sure how to use it yet. I’m hoping to use the mod bus sensor and switch that home assistant already has using these commands.
I have contacted polyaire about how to wire this up. I have a USB to rs485 converter but I’m not sure where to connect up ground if I need to connect it up at all. I have heard that rs485 should really have a common ground between components. I asked polyaire about this and they have said they’d get back to me.
If polyaire allows it, I hope to setup something and be able to share it on this post. I’ve noticed that this is new territory for home assistant and I’m hoping to give back. However, I believe only Australians will benefit from this.
