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.
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?
