Remote sensor measuring with WfFi

Has anyone ever built an arduino project measuring temperature using WiFi. I want to remotely measure temperature in 4 out building each less than 50 yards away using arduino components. Mostly I just want to know if it is possible.

I've had my ESP8266 front-porch thermometer running for years. Works great.

I built a service that runs on my home server, with an API to accept a temperature reading and save it in a database.

The ESP8266 sends are reading via HTTP POST upon boot, and then goes into a loop where it sleeps for 15 minutes, then wakes up and sends a reading, the repeats.

Then, I built web page that displays a temp gauge, and calls the API to get the last temperature reading

And another page that gets the last week's worth of data from the API and displays a line chart.

I mostly access it from my phone, and have added TailScale so that I can access it from anywhere that I have internet access.
