Dim orange light on V3 with weak connection

Anyone know a fix for V3s with a dim orange light and a weak signal? Also what causes this?

Let’s start with basic troubleshooting – can you share how it’s wired right now, and to what power source?

24V power supply > 5V via buck converter reading 5V output. 3.3A. Build hundreds of units this exact way so it’s not the wiring. Tried using micro usb as well as backfeeding through screw terminal block just to be sure, same result. Seen it happen a few times and usually just discard the chip but curious to know causes the issue and if there’s a fix.

If you enabled the WiFi power save mode, the LED will go dim and WiFi will be disabled. Long pressing the button will temporarily enable WiFi, until the next power cycle. You’ll need to turn that off in settings to keep WiFi enabled.

If your LEDs aren’t doing anything, then it might be a brown out / power issue, and might need a power cycle to come back.

Running into this again (dim orange light, loading cube forever won’t connect) so I suspect the wifi disable button got pressed by accident but when I reset the controller and it lets me connect via AP mode it Client Mode but once connected it still will not load once for me to access the settings to even check the wifi disable button. What else could be the issue?

If the LED is dimmer than usual, it is in WiFi disable mode. Hold the button for 5 seconds to turn WiFi on. The LED will flash twice. WiFi disable mode setting has not been changed permanently though, and will be off again on next power cycle, so you want to get to settings to disable it.

However, if it was not in wifi disable mode, it will switch to setup mode. The LED will flash more than twice.

You can also configure settings in AP mode, which might be handy if the PB is having trouble connecting to the router, and can be used to verify that WiFi is working normally and not obscured by metal, wires, cases, etc.
