Zdravím,
V http lze nastavit parametr refresh
https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers/Refresh
který způsobí opakované načítání stránky.
A dívám se, že pracujete s esp8266 s "originálním" firmware, který se
ovládá přes seriový port AT příkazy. Mě to přijde strašně těžkopádné,
nechcete do toho nalít svůj vlastní firmware ve kterém si uděláte co
potřebujete?
