Hi All,
I have esp8266 wemos d1 mini programmed as webserver.
2x ds18b20 temp sensors and 3v3 relay.
its simple code triggering relay when temp reaches 25 degrees in 1 of the probes.
using html, javascript, and ajax.

when I have IP address opened in web browser it all works perfect, relay triggers every time, but when browser is not opened, code doesnt work.
I wonder why digitalWrite inside void loop() wouldn't trigger relay without web browser?
is this normal behaviour?

the problem is in your code

found the problem. Posting here just in case there is anybody with similar problem,

loop() was missing this line: sensors.requestTemperatures();

sensors.requestTemperatures(); was placed only inside handle on connect, thats why it was only working when browser was on.
