Had a bad moment a couple of nights ago when our small chest freezer malfunctioned . It's down in the cellar and doesn't get checked often so
we don't really know how long it was offline . A lot of stuff partly
thawed but we managed to save most of it . Thing is , after I unplugged
then replugged the unit and rotated the temp control it came back on and
is cooling . My question is what is considered a normal range of temp
change ? Without touching any controls or even opening the lid it's been varying from -20°F to +5°F . It's mostly empty so I know that will have
an effect , but 25° seems a bit of a wide variation .

Our upright freezer rarely varies my more than a couple degrees, maybe
5-10 when its been opened for a few minutes organizing or searching for something. Maybe only a couple when its closed. A chest freezer should
be much more stable as the cold air doesn't "pour" out.
A "trick" to know how long a freezer has been out is to put a glass of
water in and let it freeze, then lay a dime on top of the ice. The ice
will sublime away over time, but if its water or the dime is sunk in the
ice you know it melted. The glass of water needs to be replaced from
time to time because of the sublimation (that's my best guess as to
water loss) over time.

Yeah , I was hoping but it looks like maybe the temp control is going
TU . I guess I'll see if it's going to be cost effective to replace it .
It's not a crucial part of our storage , but it sure is convenient to
have it . Can't complain , it was gifted to us from our son after he got
an upright unit .

upright more conveniently located and more convenient item retrieval.
Residen IT geek came up with a monitoring system for both the freezer
and the adjacent "daddy pop" fridge. the mostly full freezer runs
about a 150 minute cycle between -19.5 and -11.5 with an average of
-15.1 deg. C. while the fridge cycle is 60 minutes and 5.6 to8.6 deg.

...My question is what is considered a normal range of temp change ?
------------------------
My Magic Chef compact refrigerator has a differential of about 10 F
degrees , which I first measured and then confirmed from their tech
support. A mechanical bimetallic thermostat needs a temperature
differential to power the snap action that inhibits contact arcing.
I measured it with a thermocouple passing under the door gasket, with an inexpensive Ecowitt data logger, and with an Oregon Scientific remote
that communicates with the base station through the door, or the gap
around it.
My 12V Alpicool freezers have electronic thermostats with adjustable differentials. I have them in the kitchen area where I can watch them
because they aren't completely reliable, though they haven't thawed any
food yet.

 I just ordered a temp alarm unit . Has 3 temps displayed , 2 from
sensors and one ambient . If the transmitter range is long enough I'll
put one out in the freezer in my shop area in addition to the one down
in the cellar . Guess I better order some more AAA rechargeable
batteries too .
I would use Lithiums in the frozen space remotes. They last for years in
my outdoor remotes. Rechargeables generally have less capacity and you
might not notice when they go dead, unless that causes an alarm. Compare
the operating temperature ranges: https://www.energizer.com/batteries/battery-comparison-chart

I wish I'd seen this before I ordered ... looks like I'll be ordering
some lithiums , I was concerned about the low temp limits of NiMH
batteries .
I've had Energizer lithium AA in my remote weather station (Accurite)
for nearly 3 years without changing them, About two years ago I
stocked up on replacements from Costco (20 for $19.95) and have only
used two of them in a different application.
