Hi
I have code for water irrigation system im using 2 wemos d1 have uploaded same code to both and it works my system is a bit big for watering low water pressure thats why its split into 2 one wemos controls a relay that opens a valve this is timed to water every 6 hrs ,the other is the same but waters an hr later and opens another valve ,i want to control these by phone aswell my question is do i need 1 wemos to do both ie 2 relays or can i have both systems on the same app and run indepently

the simplest thing would be for the ESP8266 devices to run an access point with web server
the relays etc could then be controlled via a web page
this would involve two access points web pages for you to connect too
a slightly more complex solution would be to connect the two ESP8266 devices using ESP-NOW and one runs an access point Web Server which controls both devices
…or connect as a client to your local wifi, and do the same thing.
Why not cut your problems by a lot and use only one WeMos device, it has more then enough computing power to do what you want.
