I'm still using these at three different locations, and together they've recorded 9 seasons. The only new issue is that one of them is now dead after this lightning strike. I haven't investigated if it's completely fried yet. It's still only August so it's a bit down on the list of things to repair. I lost a snow depth sensor in 2008 as well to a lightning strike. I should really disconnect it completely in Spring... During my 9 years where I live now, we've had four lightning strikes within 100 meters, so I obviously need to work more on lightning protection. Surge protection and isolation by wifi have only helped to a certain point. There definitely is a link between damage and the length of the wire connected to the sensors, so I need to shield my wires and ground the shielding properly. I've been thinking that putting the wires inside copper pipes should help, but copper is incredibly expensive. So I'm considering aluminium tape instead. If it only offers 50% protection compared to copper, it's a good deal at 5% the cost.
