Not sure what your method of data reception looks like but many of us have moved to CAO Wireless Tag sensors.
These sensors
- require a common Tag Manager,
- receive signals from about 700' or more away,
- take one CR2032 battery (some larger units take the 123 now) and last about 8-12 months per battery
- are about 1.25" square x 1/4" thick
- also send Rh, lumens, geographic position, movement on 3 axis,
- send temperatures to 0.001 C, reading accuracy to better than 1%
- cost about $25 to $40 CAD each, Tag Manager about $20???
- can send data in every Ethernet method I have ever heard of, based on many methods of trigger, support email, IFTTT, push notifications, REST URL support
- supported by many mobile apps that can talk to you if desired
- beep & flash to be located if needed.
- temperature range from -40c to +40c
- produce cloud reports, including comparison graphs, etc, etc...
- support Alexa skills to vocally report temperatures, humidity to come...maybe?
