Need someone to recommend a wireless technology/protocol for a timer based obstacle course.

Not sure if this is the correct sub to ask but I am building a timer based obstacle course and need someone to recommend the best wireless protocol for the job.

  • There will be one button at the start and another at the end.

  • There will also be a raspberry pi to receive data from the buttons.

  • When the first button is pressed, it will send data to start a timer on the pi.

  • When the next button is pressed, it will stop the timer on the pi.

  • The pi will then upload the time to a database.

  • The buttons can range 15m to 50m from the pi

Which wireless technology would be good for hooking up the button to send data?

I would use wifi for the buttons with an esp32, however I found out that wifi kills battery life meaning the buttons would barely last for over a day.
