Please note: the existing ball valve must be in
good working order. It must open and close
smoothly, with minimal effort, and it must close
fully, shutting off the water completely. The
Bulldog Valve Robot is not able to correct
mechanical issues of the ball valve.
Your Valve Controller connects to the internet via
a YoLink Hub or SpeakerHub, and it does not
directly connect to your WiFi or local network. In
order for remote access to the device from the
app, and for full-functionality, a YoLink hub is
required. This guide assumes the YoLink app
has been installed on your phone, and a YoLink
Hub or SpeakerHub is installed and online.
If installing the Valve Controller and Bulldog
Valve Robot outdoors, please refer to the
environmental range specifications found on the
Valve Controller product support page. While
these devices can be installed outdoors, it
should be protected from rain and direct sunlight
by an enclosure or overhead cover, such as a
rain hood.
