It will be on the outside of my house and was thinking if it was removable I would put it inside when away for extended periods of time . Since it is not removable I guess theft is not an issue
Mine is located in the city, on the outside of my house, facing the street, and has survived several northeast winters.
You could always get the plug-in version of the wall connector or make your own. That way you could just bring the entire unit inside if you will be away for a long stretch.
I can say much the same; I bought my Clipper Creek HCS-40 EVSE in late 2016, for the Chevy Volt I'd begun leasing, and it's installed outside, in clear view of the street. Thus, I've had it for about three years with no problems, other than occasionally finding my car unplugged, which I assume was the work of local high school students playing pranks. (I live a few blocks down the street from the local high school.) This unplugging behavior has happened about half a dozen times in total, so it's not been common; and of course Teslas, unlike Chevy Volts, lock their charge ports, so it's not happened since I replaced my Volt with my Model 3, about six months ago.
A question for @Biscuitman: Are you talking about the Tesla Wall Connector or the Mobile Connector that comes with the car? The former carries a NEMA 3R weather rating, meaning that it's safe to install outdoors in the rain or snow. The Mobile Connector carries no such rating. Although I've seen reports from people who've used it outdoors for months or even years without problems, I've also seen reports of failures when it's been used in that way. Personally, I wouldn't risk it except by mounting it in a NEMA 3R or NEMA 4 enclosure. If the enclosure has a lock, that would also deter theft. Short of such an enclosure or other measures, a Mobile Connector that was plugged into a wall outlet but not plugged into the car would be very easy to steal. That's another reason to favor a Wall Connector for outdoor use, since most Wall Connectors are hard-wired and thus harder to steal.
