Turn off WiFi in Powerwall Gateway?

BLOT: Is there anyway to configure or turn off the WiFi in the gateway?

My two Powerwalls were recently installed. The gateway is hardwired to my gigabit ethernet network. The WiFi isn't being used. But it's still active, and on 2.4GHz WiFi channel 10. My two WiFi access points are sitting on 2.4GHz channels 1 and 6 so that they don't interfere with my ZigBee devices, which are on ZigBee channels 23 and 24. WiFi channel 10 overlaps with those ZigBee channels.

Given I won't ever be using the WiFi that is in the gateway, is there any way for me to turn it off or change the channel it uses.

Not sure you can turn off Wi-Fi usage in the Tesla Energy Gateway (TEG). But the channel the TEG uses is based on the Access Point (or a Wi-Fi equipped and enabled router) uses. So if your access points are on channels 1 and 6 your TEG should use channel 1 or 6, depending upon which is stronger. Is it possible your TEG is not using your Wi-Fi or your router has Wi-Fi and it is using channel 10?

The gateway has it's own WiFi access point built it and it is listening on it's own SSID at "TEG-xxx" (on channel 10). They do this so that you can connect to it like this: Connecting to Tesla Gateway | Tesla Support

My gateway is connected directly to an ethernet switch. It's not using WiFi.

I assume you were able to change the IP address of the TEG to match your network. Mine is 192.168.0.xx

If the TEG is connected to the home network via WiFi, does it still broadcast its own network? That would eliminate all the extra beacon traffic.

If nothing is using the access point on the gateway I don't think there is any significant impact on the network. Yes the SSID is being broadcast but I don't think you will have any channel interference.

Dooh. Forgot all about that since I connect via ethernet only.

Even if the TEG doesn't transmit anything, it actually eats up a fair bit of bandwidth just broadcasting its beacon. See:

SSIDS overhead effect on channel utilisation - WiFi
Revolution Wi-Fi: SSID Overhead Calculator

So there's definitely a benefit in trying to disable that wireless interface. Or at least moving it to a channel not used by the homeowner.

I further second this request. I actually joined the TEG AP from my iPhone to check configuration and next thing I know all of my other iOS devices that share my iCloud account are connecting to the TEG wifi network instead of my home network and then none of them get internet access (obviously). So I had to go forget that wifi network on all my other iOS devices. I’d like the TEG wifi AP to be disable-able.

Inside that thing there is a Neurio power meter, which connects via Wi-Fi to the gateway computer. So, the meter is a client to the gateway's AP. If you do a Wi-Fi packet capture, you'll see this data in the air. The interference you'll be seeing will not just be beacons, but the actual power meter data.
There is an option for that meter to be connected via RS485 serial but they don't generally install that. It's a pity, but by using Wi-Fi they avoid splashing out for that extra cable between the two.
The channels that the gateway picks for its AP are stupid. They should be either 1, 6 or 11. It's poorly designed by people who don't know Wi-Fi very well.
I have my meter connected via serial no Wi-Fi, but the beacons still exist (at 1Mb/s bitrates too damn it) but I can live with it.
What you could try is connecting its Wi-Fi to your home network anyway, even though you have it wired. It (I'm going to assume) should still prefer to communicate over Ethernet if it's like any normal Linux box which will give Ethernet a lower metric, but by being on your network it would force its AP function to use one of your channels because it only has the one Wi-F- radio.

Tesla is coming by tomorrow for the town inspection, so I'll ask about using a serial cable there and disabling the WiFi. But if that doesn't work out, I'll probably do you as you suggest and join it to my network (and then see what network it actually talks upon).

Did you find a solution? I too am trying to shutdown this wifi.
In the end I found no actual interference or problems with either of my Zigbee networks (one on a Smartthings v2 hub, one on a Hubitat C-7 hub), so I did nothing to the Gateway's WiFi.

That said, the approach I was going to try was the one suggested above, which is to join the Gateway's WiFi to my own 2.4GHz WiFi so that it would hopefully stop broadcasting out it's own beacons on channel 10. But since everything was working, I just did nothing.

for what it's worth, I set up the TEG to be on my wifi in addition to the ethernet and it did indeed change its channel to match my wifi channel instead of using channel 10.

Is it a good thing that TEG WIFI follows the AP channel?

I have several WIFI devices in my garage area where I have the TEG gateway-2, such as WIFI irrigation controller, WIFI smart switches, and WIFI security system. I have been noticing that my devices are failing to connect to my AP and observed that the signals strength of TEG WIFI is overshadowing my AP signals near these devices. I tried moving my AP channels, but TEG is keep following the same AP channel and I can not prevent it from interfering my other device connectivities.

If TEG WIFI cannot be turned-off, I wish I could set it to use different channel or be able to reduce its signal strength.
