Most of them does NOT.
And even if it would be possible,
it would need an extra module,
only awailable from the manufacturer,
which would take weeks or month to import + pay custom tax + VAT
which usually costs $100+
and the API is 95% not available.
I know this, because I've tried already.
Also most restaurants are buying freezers ad-hock. So usually each of them is different. (And most of them the cheapest one.)
That would make it an "impossible huge task" not worth it.
In my country, Poland, I use other devices from this company but they have ones for one sensor via 1-Wire. Set include sensor. Power supply from POE or external 12-24V DC.
Is there are a huge amount of temp sensors for freezers in the market?
Why would you need an extra module?
You could reverse engineer their proprietary ADC using a osiloscope and some measurements taken from a controlled room using another sensor, if they dont provide the way the signal has to be read. It just takes a huge amount of time when you never done it before
I just dont believe you should drill another hole in the freezer to add your own sensor, unless it is possible to keep its thermal insulation intact, while not comprimising their insurance on those freezers
check the earlier post - Temperatures in Pizzeria freezers - #10 by PizzaProgram - it sounds like there are a variety of different types of freezer - that are physically separated by some distance - so a simple add-on retrofit would suit better than trying to hack each one.. Flat ribbon cables can be used through most seals without compromising them or needing holes.
