Does the AlorAir Sentinel HDi65S Restart After a Power Outage?
Yes. AlorAir says the Sentinel HDi65S has an automatic memory/restart function. After power is restored, the unit automatically restarts and returns to the previous setting rather than requiring someone to crawl back to the machine and switch it on manually.
That is a small feature until the dehumidifier is installed in an out-of-the-way crawl space. Then it becomes one of the more practical questions to ask before buying.

What AlorAir Says
On the HDi65S product page, AlorAir lists Memory Starting as a feature. Its manufacturer Q&A also says the unit has auto reset and humidity-setting memory.
AlorAir repeated the same point in a 2026 community answer about the Wi-Fi HDi65S, describing an auto-memory and restart function that resumes the same settings and mode after a power interruption.
Why This Matters in a Crawl Space
A normal room dehumidifier is easy to notice after an outage. A crawl-space unit may sit out of sight for weeks. If a dehumidifier stays off after a brief power failure, the first warning might be humidity climbing again.
Automatic restart removes that particular failure point. It does not solve a tripped GFCI, tripped breaker, damaged unit, pump problem, blocked drain, or loss of power to the receptacle itself.
Does It Remember the Previous Setting?
AlorAir’s more recent community response says it resumes the same settings and mode, not merely that power returns to the machine.
Bottom Line
The Sentinel HDi65S is designed to restart automatically after a power outage and return to its prior settings. For an unattended crawl-space or basement installation, that is a meaningful ownership feature.
