OpenSprinkler Forums Hardware Questions Wireless valve control using ESP8266 Reply To: Wireless valve control using ESP8266



You asked ‘Is it possible to use the ESP8266 (or similar) to become a remote switch to control a valve/relay?’ — assuming I understand it correctly, I think the answer is yes. First, OpenSprinkler 3.0 uses the same OpenSprinkler firmware API:
you can use a script, or a program, or a command line tool to send command to the controller to trigger a zone or a program. I assume that’s what you mean by ‘remote control’.
