- Sun May 30, 2021 5:26 am #91507 Hi! I have two ESP8266 boards (with a temperature sensor connected to each one), one is in my house and the other in my parents' house, so each one is connected to a different wifi.

Is there any way to update the code of the two boards at the same time over wifi?

with Arduino see the esp8266-Arduino ArduinoOTA library

- Tue Jun 22, 2021 11:11 am #91737 Yeah, you can do that using many 3rd party libraries, its called OTA short for "over the air". I have once worked on Blink OTA for esp8266.

This library allows you to update your board's drawings through WiFi or Ethernet.

The library is based on the WiFi101OTA library for Arduino.

this is a description from my generic ArduinoOTA library.
for esp8266 over WiFi esp8266 arduino boards support package has a bundled ArduinoOTA library specialized for esp8266 WiFi
