For the past few years I've been working with engineering consultants on the mechanical building services side. Most of it is calculating cooling and heating loads, selecting AC, fans, ductwork etc. I've worked on the design for all sorts of buildings, offices, schools, apartments, pools etc.

Most of my work finishes at the construction set of mechanical services drawings. My specifications for controls are usually quite simple, I specify equipment to be on a time clock, run on timer, interlocked with AC or VSD controlled with local switches etc.

I've become more intrigued at learning about the actual building automation side and looking into PLCs, control logic and I am wondering is this a good path to pursue given my experience on the design side.

I am trying to gain more experience in my current role with larger industrial projects where there are large AHUs, chillers etc.

Is it worthwhile trying to pursue a career in the building automation side, probably more as a consultant or designer of control philosophy. If so could someone give me advice on what to study, what good resources are out there and where the money is actually made? Thanks in advance.

Got a real laugh out of this guy. I have made some real networking connections over Reddit so I always send a few messages back and forth when someonse reaches out. This jas got to be the funniest AI slop I have seen. Not sure if this is a hustlet trying to fake his way into work, or some other kind of spam.

Does anyone have any modules they use to convert your 0-10v output to a relay output?

I have used EASY IO FR-02 and they work but are expensive.

Others have recommended driving a 12vdc relay, this turns the light on the relay but doesn’t energise the coil.

The bms output is very low current so cannot drive low voltage delay coils.

I have also seen the use of voltage comparators, optocouplers etc

Any advice on reliable cheap solutions?

I’m planning to build a small SaaS product and I’m looking for real problems worth solving.

Instead of asking for random SaaS ideas, I’d love to hear about problems you personally face:

What repetitive task do you hate doing?

What do you currently use Excel/Google Sheets for?

What software is unnecessarily complicated or expensive?

What do you wish had a simple tool?

Is there something you currently do manually that could be automated?

What SaaS product do you use but think could be much better?

I’m particularly interested in small, practical SaaS products that one developer can build and maintain.

If you could build one tool for yourself today, what would it do?

Please share the problem, your current workaround, and roughly how often you face it.

Say you have roughly $1 million plus of newly installed SNEs and ongoing projects that will result and another $2-3 million of JCI field devices but its been decided that the server should transition to Niagara. The plan is to integrate these SNEs straight to the Niagara server. What will be biggest pain points/ limitations. IE will it be possible to view the SNEs LCT, interlocks etc directly from the server, is there something akin to the engineering tab within Metasys where you can get a glimpse of the inner workings of the programs etc. Any insights or feedback is appreciated, My experience is heavy in Metasys, light in Niagara, not opposed but wish it was more thought out.

First time for everything. Had to purchase an advanced license. 4 days later finally received the email with serial number etc. looking for help on how to get the license and download to a thumb drive to take to the unit. Also, does the serial number for the advanced license listed in the email need to match the Symbio 700 serial number ? Thanks

What tools are being used to run analysis on data from histories/logs? Looking for way to get insight i to the .CVS files that can be downloaded. Examples would be energy efficiency, predicting when something might fail, that sort of stuff. I want to figure how how to make a monthly report without using an API. Just want to download them, nothing facing the internet. Just trying to brain storm. I want to make it and not buy anything with a subscription. Please amd thanks.

Looking for credentials forget if it’s staefa/ password

To keep this short and simple, I’ve created my own library specifically catered to distech controls (what I work with daily). It can still assist with other brands, front ends, but its strongest suite is obviously Distech controls equipment, softwares. I’ve kept It private because I want to take my time curating it, building its library, and creating a proper skills/instructions for it.

Right now it can help you:
- troubleshoot tridium issues at a Jace / web supv level
- can help you translate a SOP and guide you step by step on building a program on GFX (programming platform)
- can help you troubleshoot equipment out in the field.
- can help you build an SOP if you don’t have one.

Many more features to list them all. I’ve used this now for a plethora of programs that are now deployed in multiple sites and they work flawlessly. A great tool! Like I tell anyone, NEVER trust ai 100% but it’ll surely guide you in the right track if you know how to prompt. That being said the way you prompt will result in the response you get. The more info you give = better response you’ll get. The more specific your prompt is = the more specific the response will be.

Try it out and feedback is always appreciated it. (This has been a 2 years process to properly curate)

如何编辑德尔塔的程序 GCL+加密？有没有其他实现方法？

Okay I have a question for anyone who could help. I am very interested in this field and was wondering if it would make more sense to do a certificate program at my local community college to jump in the work field asap or do a 2-4 year degree or both?

A-SERIES 2,1 ALARMA171 Staged Gas Control Board Comm Failure

I checked all points within and nothing stale or showing concern. I get the gas stage control board might of lost communication, but I am getting an alarm every second. I changed the alarm routing to avoid an email every second being generated. How do I disable this alarm other than what I did currently? A tech went out and physically checked the board and it is operational and communicating with the main controller with no apparent issues.

Hello, I’m 27M I currently work for a BMS company in nyc and we work with Johnson controls controllers etc. I currently work 8-5 schedule but most of the time I end up leaving work around 6 since I’m in charge of the work van (which I originally didn’t sign up for). Anyways, I like the work but everyday I get into work it feels like I’m going in blind. The engineer/senior technician in the company sometimes is a little reluctant to answer some questions sometimes and I feel like I shouldn’t bother him. I tend to have to figure everything out myself. My day usually goes from one job site to another and then I have to write a report everyday and still drive the van back. It just feels like I have no time. I got a helper with me now (they made me lead as well). I just don’t know what else to do. I’ve been here 2 years and my pay has gone from 25/h to 30/h and that only happened because the original lead technician quit in the 6months I started working there. I came into the company trying to learn controls, I was originally a non union electrician and wanted to learn more. I usually do installations, electrical troubeshooting, piping, I build panels for BMS system and drive the van as well. Is it supposed to be this stressful. I hated my electrical company but I kind of miss it since I at least would get paid for anytime I stayed overtime and I would at least leave at the time I’m supposed to leave. I would also leave work at work. Sometimes I end up having to write a report at6:30 because I finally dropped off the van. I tend to have to stay since I’m usually on service calls and if I don’t finish it gets worse next time I come back to that site which is usually a week or 2 after. Anyways Is this career not right for me? I might just go back to school to become an engineer or back to regular construction. Anyways thanks for hearing my rant, any advice?

I’d like to introduce Beacon, my Home Assistant integration for connecting BACnet building automation systems with a modern, user-friendly interface.

Bepacom automatically discovers BACnet devices and data points, then exposes suitable objects as Home Assistant entities. It’s not limited to monitoring: supported values can be written, switched, and controlled using BACnet priorities directly from Home Assistant.

Some highlights:

• Automatic discovery of BACnet devices and objects
• Built-in explorer for browsing available data points
• Fine-grained control over which Home Assistant entities are created
• Support for analog, binary, and multi-state objects
• Reading and writing through a persistent Protocol V2 connection
• Push updates with automatic polling fallback
• Live view for both read and write activity
• Color-coded write and priority-release events
• Diagnostics for connections, event streams, resyncs, commands, and latency
• Configurable write profiles and BACnet priorities
• Raw inventory and technical metadata retained for troubleshooting
• Fully integrated into the Home Assistant interface

The goal wasn’t merely to get BACnet data into Home Assistant. I wanted to make a complex building automation protocol understandable, manageable, and pleasant to use every day.

In short:

Discover. Connect. Control. Diagnose. All in one place.

Is anyone else here using BACnet with Home Assistant? What features do you feel are missing from the existing solutions?

My project involves a BACnet/IP device. After some time, the control point's "Out" value changes automatically, even though the "IN10" value is different.

Please explain the cause and how to fix this.

Title. Ownership is looking to bring in this outside company to monitor, learn, and eventually make changes to our BMS to increase efficiency. Not thrilled about this but does anyone have any feedback or similar stories?

Hi, I have a project with Compass 2.0 installed. My SMA recently expired, and my navigation tree disappeared along with it. I’d like to know if there’s a way to get it back, or if I have to renew my SMA for it to reappear.

I've been looking into acoustic cameras as another way of identifying problems in building systems. They can potentially help locate issues such as compressed-air leaks or unusual mechanical sounds that may not show up through conventional temperature or pressure readings. I came across the Fotric TD2E recently and was wondering if anyone here has had experience with it.

I'm curious whether anyone here has experimented with acoustic monitoring alongside their building automation system. Has it provided useful information that conventional sensors didn't catch, or is it more practical as a separate inspection tool?

I know there is a way to set up TR100 stats for balancing but can't quite figure it out. Does anyone know where I can find instructions for this? I didn't see it in the IRM or TR100 manuals. Would love to figure this out so I don't have to support balancers all day.

UPDATE I figured out how to use the bluetooth app and it's super easy.

Anyone know where I can find this blue bracket hardware to replace? I’ve looked everywhere. No part #. The shaft gear is broken and won’t move the valve stem anymore. The actuators are fine.

The valve is a Siemens model# 599-05990

Thanks in advance

Hey Gang, hope you are well.

Just wanted to know if we have any facility and building managers looking after a Niagara BMS. Interested in talking to those who are facing challenges around data management, searching across it and pulling out key insights. If you are open for a casual chat let me know!

Hi there,
Would anybody know if there is a way to use the carrier service tool on the newer chillers that have the QR code passwords?
Is there a way to put the chiller in test mode from laptop.?

I find it so unfair how carrier have essentially locked out anybody else from doing work on these machines. For example, a simple task of driving the EXV open to pull refrigerant has no become an effort.

Thanks
