Might be a moot point, but some home alarm systems (like my ~obsoleted Panasonic) integrate temperature sensors into the mix. Each sensor can be configured for various settings, notification and/or alarm parameters.
If you could justify the expense of such a system, for its' capabilities beyond your basic icebox sensor readings, it might be worthwhile at least looking at them.
My system can support up to 50 sensors, cameras, etc., all with just one hub unit and a router connection, which isn't required for a minimal local usage (a router/gateway of some type. I use a cellular wireless ATT "Homebase" one, running on an additional fairly low data allowance 4G-LTE cell line, everything held up in a power fail by their own UPS batts).
The system has a very nice comprehensive app for I/O, comes in Android and Apple, but not Windows/PC; it is regularly maintained and upgraded.
I use old cellphones and cheap tablets as interfaces for monitoring and configuration, system supports 8 devices (this system runs on 3 or 4 different radio bands/protocols-- DECT*, wifi, mobile...). The router supports the I/O devices via wifi. For minimal/basic use there is a keypad panel and keychain remote.
Plus your ubiquitous carry-with smartphone for remote monitoring/config use.
* Mentioning DECT: been wondering why it isn't used for wireless PWS's. It's a standardized wireless interface protocol that could make all of the various weather station components interchangeable. Supports virtually any data transfer mode and device profiles/classes. Has a healthy range (660ft-3.7mi) and interference resistance.
(of course, the 'proprietary' mindset of the PWS vendors is why this will never happen)
