I've heard of this before. How hard is the install of inkbird controller? Chest freezers from I see go to negative 18C. My mead needs about 0C to -4C. Can I get with install of this part?

After reading little more...you insert temp sensor into a refrigerator and this device controls power to cool it. Seems simple.

Find some used 7cf chest freezer and put a inkbird controller on it

Stick a push notification on the search term on Facebook etc

There are quite a few that get listed but they go fast.

I'm searching for options / solutions to cold-crash my mead. I'd like to be able to do 2 x 5 gallon carboys at a time. 
What's the good solution mead community suggests.
