What happened
Empty cabins fail silently. A mid-week alert beat a Friday arrival to frozen pipes and a flooded crawlspace.
Typical Pro trial → Member or Pro subscription after winter. Your results depend on sensor placement and alert thresholds.
Story FAQ
Do you need SMS for a cabin?
Email and Pro browser push were enough here because someone could respond within two hours. SMS helps when you’re offline hiking.
How many probes?
Two: living space for comfort context, crawlspace for the freeze risk that actually matters.
