Wifi networks and home automation systems are expected to last 50+ years.

I was reading up on the life expectancy of different building materials when I came across this gem.

Screenshot is of page 122 https://www.portseattle.org/sites/default/files/2025-02/SEA-SIPP%20Technical%20Report%20Appendix%20C%20Life%20Expectancy%20of%20Building%20Materials.pdf

I guess the ethernet cables could last that long, but they rate house wiring to a lower lifetime. Ethernet cables are not "wireless", however.

The only other wireless systems I can think of are garage door openers, but they are definitely not expected to last 50 years.

Do optical smoke detectors decline? They dont have radioisotopes anymore, so should work reliably for years?

    Idk, but I'd expect all sensors to degrade over time for different reasons and especially if they are not cleaned and maintained regularly.

    I've got an optical that is recommended to replace after ten years. I find it a reasonable investment.
