Would anyone know of a good IOT Gateway that is WIFI based, accepts analog inputs (4-20ma, 0-5V ect) and then can send that data via MQTT?

I have a device I am using...but it is getting increasingly harder to find supply of it.

Any ideas?

You could just use an ESP32 flashed with Tasmota or similar firmware.

Hello,

MQTT gateway + Remote I/O with anaalog inputs. However, you have to connect MQTT gateway with WIFI AP.
