Giv-Gateway WiFi has died?

I had an All-in-One battery installed last week and it's been working quite well not withstanding a little bit of patchy behaviour; such as randomily going idle for no particular reason, requiring a restart of the All-in-One inverter to get it discharging again.

With the All-in-One you actually have two devices connected to your network; the Giv-Gateway and the All-in-One. This means there are two GivEnergy WiFi devices to manage, the Gateway (which has a SSID of it's own AP beginning WJ) and the All-in-One (SSID beginning WK).

All of a suddent, today, I've been having problems connecting to my GivEnergy system locally (in the App) or via GivTCP. On investigating I found that the WiFi in the Giv-Gateway seems to have totally given up the ghost. It is no longer attempting to connect to the network (as far as I can see) and it isn't even broadcasting it's own network anymore (I've been and stood right next to the Gateway with a WiFi scanner and no AP is being broadcast).

On my LAN management I can see the All-in-One device is connected, and hasn't had a single drop since it was installed. But the Giv-Gateway....I can't see anyway that exists to try and 'restart' the device. I'm a bit stuck and was wondering if anyone has any hints/tips on how I might get the Giv-Gateway WiFi back alive again.

Quick reply to my own post, just in case anyone is searching for this in the future.

I've managed to get the Gateway WiFi back online. To do it I went through the shutdown procedure for the AIO (Switch off with button, battery breaker off then AIO breaker in Gateway breaker off), then I switched off the load then grid breakers in the Gateway. Obviously this cut power to the whole house.

I gave it 10 seconds then reversed the process to bring everything back up and glad to say the Gateway connected to my WiFi again (and is broadcasting its own AP as well).

This is obviously not ideal but I'm not sure there's any other way to bring it back to life. I must admit, I'm surprised the number of times I've had to go and physically restart this equipment so far (i.e. more than zero times is bad, and I must be up to a handful now). I hope there's some stable firmware updates in the works because at the moment it feels decidedly "beta".

Well that was short-lived, the Gateway has just done exactly the same thing. Disconnected from WiFi and just totally disappeared. It is no longer broadcasting its own WiFi so I suspect it has once again crashed. I don't particular like the idea of having to bring the entire house offline just to get my battery system working. One of the main selling points was trying to avoid power-cuts!

Seems good time to contact GE help and get their experts to remotely look at your setup?
