If a specific value is found in the fine dust meter using my Arduino Naro, it sends some text to the node mcu of the air cleaner. Is it possible to turn it on when the air cleaner receives A and turn off when B is received?
Device A is dust sensor using arduino nano.
Device B is air cleaner with power switch.
Device A detects specific dust value.
Send message Device A to Device B
Turn on the air cleaner or turn off.
