WebRelay Integration Notes
Canāree i1 Supports sending HTTP Commands to a WebRelay device via the
Ethernet or Wifi network.
WebRelay is an electrical relay (or electrical
switch) with a built-in web server. The relay can be turned on, off, or
pulsed using a web browser or Canāree i1. It has a long history of reliable
operation in many applications including remote reboot, industrial control,
security, and remote control and monitoring

In this solution each Canāree i1 can be configured to connect to a
WebRelay’s URL to start or stop the relay, and this can be done automatically
at specific PM Limits for PM1, 2.5 10. In this configuration the relays will be
turned ON whenever the PM Thresholds are exceeded, and turned OFF only
when the PM Thresholds are no longer exceeded. This can be used to
control Exhaust Fans, Air Purification Systems or UV Lighting devices.
A manual Relay On/Off mode toggle is provided for testing the relay. To
configure Canāree i1 for a Web-Relay you must enter the stop-start URLs
before enabling Relay Mode on the device. The following commands are
provided as examples when configuring WebRelay using their default values.
●
%Wrelayurls=
http://192.168.1.2/stateFull.xml?relayState=1,h
ttp://192.168.1.2/stateFull.xml?relayState=0
ON and OFF URLs to HTTP GET for your specific Web-Relay use its real IP Address.
●
%Wrelayactive=1
Enable the Web Relay controls by setting this value to 1.
●
%Wlimits=[pm1.0],[pm2.5],[pm10]
Set relay PM upper-limits to auto-enable relay ON URL, for example Example:
%Wlimits=35.5,35.5,155.0
