Overview
Control4 BMS Monitor Lite is a unique driver from Janus technology for monitoring thermostat and consumption data, providing a simple web interface for viewing this historic data.
It is a perfect lightweight alternative to BMS Monitor if you only need to monitor a single zone (e.g. tracking rack temperature to confirm safe operation).
The driver allows key parameters from one thermostat in your project to be monitored (current temperature, setpoint, HVAC mode and HVAC state). Additionally, outside temperature is obtained from an Internet service, together with a temperature forecast for the rest of the day.
The solution supports any thermostat proxy, v1 or v2 - no special thermostat drivers are required. Furthermore, no additional devices/interfaces are required - all data is stored directly on the main controller, and backed up in persistent memory, so it is preserved across power cycles and even system restores. Up to 30 days' data (or 10K samples) are stored for the monitored elements, with simple navigation between daily and weekly views.
In addition to thermostats, BMS Monitor supports other data visualisations, such as water consumption, energy usage and more! See the FAQ for a full list of supported drivers.
While BMS Monitor Lite allows you to view one thermostat and one utility driver, you may be interested in BMS Monitor - which allows for any number of supported drivers to be monitored simultaneously!
Webview Compatibility
The webview interface is compatible with any Control4 UI. This includes T3/T4 touchscreens, and the iOS and Android apps*.
You can also view the interface from any browser by navigating to the following URL, substituting in the IP address of your main processor;

Can I use BMS Monitor from my phone/tablet?
You can! From OS3.2, you can now access Colour Wheel from the Control4 iOS and Android apps.
I would like a new driver type / variable to be monitored
We are actively working on this solution to bring other data visualisations into Control4. Please contact us with any suggestions or if you have any specific requirements!
I would like BMS Monitor to be translated into my language
If you would like translations in your language added, please contact us to discuss how we can achieve this for you.
