I’ve been using these:
They are not the most inexpensive though they provide an API to access the data if you are into programmatically creating your own application (if you are using the cloud based storage). For non-cloud, the internal storage is relatively large such that you can go, I think ~3months, without needing to connect with your Bluetooth device. Cloud storage seems more or less infinite. I have data logged going back four years. The internal sensors they use internally seem pretty good. The battery life is pretty good as well.
I have 15 of those with a couple of the newer version that also have an atmospheric pressure sensor. I use these for a number of different scenarios. For curing and storage, a small slice of heavy duty velcro to attach them to the lids on the jars.
