Integrating with Wacnet and Mango

@maurice ,

Without the RS485 “Ground” wire terminated (a 2-wire bus with shield) at each device communications is intermittent, which would indicate a possible 3-wire RS485 bus hardware configuration.

The power supplies are Regulated 24 VDC (Idec PS5R-VC24)

The T3000 Software is rev. Nov 29 2019.14, T3-XX are rev. 50 and Tstat8_03 is rev. 8.8 and Tstat8_04 is rev. 9.0

As mentioned in posts in another topic (T3-BB) the Tstat8’s have not had any major issues with communications in T3000 software or Yabe, but the T3-Nano (as IP to MS/TP Router) was intermittent. The only device that has maintained consistent reliable (BACnet) communications across multiple software (T3000, Yabe, Mango and Wacnet) is the T3-8o.

We will set up some tests and see if we can duplicate the issue here. From what I understand the worst case scenario is when you use a two wire connection with several devices on a T3-nano subnet, then poll the nano over Ethernet using Wacnet.

Just went to the Wacnet web site and it looks pretty interesting. More news shortly.

Yes, that’s the worst case for BACnet MS/TP communications.

Has there been any updates to this thread. What other programs are you using for a front end to control the points?

@bill ,

The Front-end program / software / GUI would only be used for monitoring, possible overrides from auto to manual and trending. Control functions reside in the Thermostat and or Controller, they are “Stand-alone Devices”. You could use the T3000 software for these “Monitoring” functions.

The Mango Automation program is quite “mature” and works quite well as a “Web Server” with HTML connections. My current issue is discovery of BACnet MS/TP devices, most BACnet IP devices are readily discovered.


@PeteR and @maurice,

I downloaded the Mango system and got that up and working. I am able to see a Big Brother and the T stat 8 as a “slave” device of the Big Brother ‘Data Source’ within Mango.

I am not sure if I can see all of the register values, but I’m also not sure if I have proper read/write permission for the BB. Is there such a thing?

When I bring in a temperature value into mango, does the value default to Celsius? Is there a way to convert to Fahrenheit?
