Description

Overview

Control4 BMS Monitor is a unique driver from Janus technology for monitoring thermostat data and providing a simple web interface for viewing this. The driver allows key parameters from any 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 each of the monitored elements with simple navigation between daily and weekly views.

Webview Compatibility

The webview interface is compatible with any Control4 T3 touch screen.

You can also view the interface from any browser by navigating to the following URL, substituting in the IP address of your main processor;

Which variables are monitored for thermostats?

Depending on the thermostat driver capabilities, the following variables can be monitored

• Temperature
• Setpoint C/F (single setpoint, or seperate Heat/Cool setpoints according to capabilities)
• HVAC Mode
• HVAC State
• Humidity

Additionally, the following data will also be visible alongside the aforementioned variables

• Outdoor temperature + forecast

Can I use BMS Monitor from my phone/tablet?

You can! Ensuring that your device is on the same local network as your Control4 processor, in your device’s native browser navigate to http:///driver/hvac_generic_bms_monitor/dist to access the BMS Monitor interface.

For iOS devices, you can favourite this web page to your home screen by tapping the upload icon, then tapping Add to Home Screen.

For android devices, you can favourite this web page to your home screen by tapping the menu icon (upper-right corner), then tapping Add to Home Screen.

WARNING due to web page caching, after updating BMS Monitor you must either re-create this favourite or restart your device to access the new updates from your device.

I would like a new driver type / variable to be monitored
