Hi, I have just installed a new Gree Aircon and get the following error when trying to add the new Aircon Unit,

"Unable to connect to the device. Please check the network connection and try again."

I have other Gree Aircon units and they connect fine so know my settings are correct.

Only thing that i can see different is other aircon units have Firmware Update V2.01 and Model Version V19.4

The new unit has Firmware Update V3.10 and Model Version V19.4 (Model ID is 10001

All units connect perfectly to the Gree App and work fine.

Anyone else have this issue and have found a work around?

I had the same problem, but with a unit I've been using for many years with this integration. It just suddenly stopped working a couple of weeks ago, but I didn't have time to look into it until yesterday.

Long story short, what solved it for me was to unplug the power to my unit for a few seconds and plug it back in, which immediately resolved the problem. It's a cliché I know, but what I'm essentially saying is, have you tried turning it off and back on again? ;)

My model version is also v19.4 and my model ID is 10001, but my firmware is v3.75. I also have it set up with the Ewpe Smart-app (which as far as I've understood is basically the same as the Gree App, but for OEM products - my unit is branded Wilfa Narvik 25, but it is a Gree unit), and that still worked even when HA couldn't connect to it.

I am sure i did try the turn it off and back on again when i first had the problem. But just incase will try again. Have it on a number of units all using that version of the wifi device
