I just spent 2 days trying to figure this out. If I had known all the hoops I had to do to get this to work i would of just bought the bluetooth version. The instructions for this product is wrong and inadequate. Here is what I did to get this to work.
1. Make sure you complete the setup first before you install the pump. I spent like 30 minutes running lines in my sump only to have to dig out the pump so I can move close to the router to finish the setup.
2. Make sure you have the right app, there's 4 Kamoer apps out there. You need the one called "Kamoer Remote"
3. You must be on 2.4g band. If you can disable 5G then do it, if you cannot then rename your 5G. If you have a mesh system unplug the satellites. Once setup is completed you can turn everything back on.
4. This is where instructions are wrong and most people are having issues. First you have to power on the pump and wait for the blue light to start blinking slowly. You need to get the pump into what they call a distribution mode. The pump is in distribution mode when the blue light is blinking rapidly. **Important** The app tells you to hold it for 6 seconds the manual tells you to hold it for 3 seconds. You need to hold it down for 3 seconds only. If you hold down the reset button down for 6 seconds you will notice it will blink red 2x, blue 1x, red 2x, blue 1x. This will not work and you will not get the pump into the right state. You only need to hold it down for 3 seconds, wait for the light to blink red 2x then let go. Wait 15 seconds and the light should be blinking blue rapidly. Once the blue light is blinking rapidly you can launch the Kamoer App. Do not launch the app until the blue light is blinking rapidly.
5. Ok now this one is the kicker. I was only able to dig this out by reading the coral vue support page. You need to give the Kamoer app permission to Location. For Android you locate the app and press on the app until a menu pops up called app info -> then press permissions and make sure Location is allowed.
I have 2 X1 PRO pumps, I was able to get the first pump connected without having to do this step. But the second pump would not connect until I did this.
I hope this helps!
