WebRelay Wireless™
Single Relay, Single Input, Up to 4 Temperature Sensors
WebRelay Wireless is an easy to use Wi-Fi enabled relay, temperature/humidity monitor, and status alerting device.
Overview
The WebRelay Wireless™ is an easy to use Wi-Fi enabled relay, temperature/humidity monitor and status alerting device.
The WebRelay Wireless has a built-in relay for controlling lights, motors and other relatively high current loads, a digital input which can be used to monitor and report the status of switch-closure sensors and a “1-Wire” port for connecting up to four digital temperature/humidity 1-Wire sensors.
Built-In Web Server
The WebRelay Wireless works well as a stand-alone device that can be controlled and monitored using a standard web browser. It can be set up and configured using simple menus and drop-down lists.
Wireless Access Point
The WebRelay Wireless can be a self-contained wireless access point that requires no additional servers or ControlByWeb devices. In this mode the WebRelay Wireless provides live, real-time temperatures or input status directly to a user through web browsers or the CBW Mobile app (optional).
Setup is simple. There is no app to download, no subscription to buy, no software required, and no programming necessary for setup or use.
Logging
Record data such as sensor data and changes in I/O state. Both periodic and event-based logging are supported.
Email/Text Notifications
Record data such as sensor data and changes in I/O state. Both periodic and event-based logging are supported.
Peer-to-Peer (P2P) Communication
The WebRelay Wireless has the ability to remotely control relays located on other ControlByWeb devices.
