Temp Sensor Ethernet Probe

Im looking for replacement or to create low temp sensor for refrigeration

perfer temp & humdity range -20 to 100 degrees

I currently have a data logger TEMPALERT wifi

WiFi 350

RJ 12 Sensor connection

We don’t have anything comparable to the obsolete TEMPALERT device (TM-WIFI350 LAN-based Temperature and Humidity Data Logger ). The only device I found that is similar is Digi-Key part# 1165-1418-ND refrigeration monitoring system from Advantech, BB-WSK-REF-2 Advantech Corp | RF/IF and RFID | DigiKey
