Maximum WiFi Password Length?

[DaveEV]

Picked up a Vue Utility Connect with the idea that if this works out nicely, I’d augment it with a Vue 2 to monitor individual circuits. Space is very tight around the utility service lines in my panel, so I doubt even I’d even be able to get the flexible CTs in there. So the Utility Connect will serve as the main breaker CTs and I’ll nest the Vue 2 under it.

Got my Utility Connect today, plugged in and hooked up to wifi and Utility Zigbee pretty easily.

But I ran into an issue with the wifi connection – my primary wifi has a pretty long password – 25 characters long – I tried multiple times, but no go. Switched over to my guest wifi and it connected the first time – it’s password is 15 characters long. Both are longer than the 12 characters I saw as a suggestion.

Is there an actual known maximum password length? In my opinion, it’s crazy to have a maximum – this is the first device I’ve had this issue…

I’m using the maximum number of characters for WiFi (63 or 64, can’t recall) and it’s working fine.

if you’re pasting your code, is it possible you’re accidentally pasting a whitespace character at the end?

I tried typing it in as well as copy/pasting it in, couldn’t get it to work with either method.

Maybe it has an issue with one of the non-alphanumeric characters in the password? The password does have an ampersand (&) in it. I could see <, > or % also as being problematic characters since these are commonly escaped as part of sanitizing the input of web applications.

Can you test your theory by temporarily changing the password on your guest network to include &.

Many years ago my home network used an extremely long random password with every character type.   When various devices with virtual keyboards became common I changed my password to mostly digits with a small number of letters and special characters to make it easier to enter.
