Working but with some difficulty
I was finally able to get it to connect but it seems that it uses something that doesn't allow it to connect to all types of routers. I tried two wifi routers on my network that both have 2.4Ghz Wifi connections and it would not connect to either. I have a cheap repeater that I use to connect my wired network generator to my wifi network (don't have to run cables to it) that I was finally able to connect it to. If not for my repeater I am afraid I would have had to return the controller and wifi device. It shouldn't be this difficult. But with this difficulty aside, the device / app is bulletproof, it works great!

Will not connect to 2.4 . To complicated to set up.
Unit will not connect. I spent hours making all kinds of changes to router 2.4 won't connect. The unit will not switch to local mode per the instructions. I basically have a 50.00 paperweight. Why can't thing nowadays just work.

it just won't connect....i finally got it connected
ive tried many attempts to get this thing to sign on and it never connects. i give up. update...i was in contact with support...it didn't go very well. i feel like i knew more then support. big waste of time. they want me to take videos of my phone. update...i went from 1 star to 3 stars. this thing took forever to connect...i literally spent about 3 hrs trying to get it connected today. changed router passwords, guest account finally got it connected. the company did send me a new unit after having problems with the first one.

Works well, Tricky to establish communication
Works well, but make sure you're on a 2.4 GHz network and follow directions. Your phone must be connected to a 2.4 GHz network you plan to use when you use the app to establish communication. I have a Gggole Nest router with no seperate names for 2.4 GHz and 5 GHz bands and couldn't get it to connect. I added a small range extender, configured a 2.4 GHz band with unique SSID name, connected my phone to this SSID, then connected to the adapter through the app with no issues. I am now able to monitor and configure my Ampinvt 60 amp chagre controller remotely.
