RESOLVED: 1/10 Second Power Outage = Sense Offline - Technical Questions - Sense
To:  @CarlT
I had the same problem you are describing happen to me 3 years ago.  Read the blog above.  My solution was to use a TD-69 relay timer.  Since I have installed it, no problems with SENSE rebooting.  It’s a cheap work-around.   You don’t need all the additional relays that I installed.  Just wire the TD-69 to your black ‘power wire’ on the SENSE unit.
