Thanks for the question WHITELEYHOME, you simply need to give permission to your irrigation guy. To do this, go to settings, devices, your timer. There is a button that says “Device Sharing”. Press that and then tap managers. A button will pop up that says “Generate Access Code”. Pressing that will create a 6 digit code. Give that to your irrigation guy and he’ll be able to control your timer.
You can also share your account email and password with him.
