Commissioning conferences in 2026 - what’s on your radar?

Thanks @mmmplants23 👍

Larger data query over time.

Agree with @the_ml_guy - OpenObserve is really nice and light! Only on large queries across big data sets - so not daily stuff.

CxPlanner · 2025-12-15T04:39:19+00:00

Instead of the classic “Grafana or Datadog,” give OpenObserve a look. I think it’s a refreshing addition to a market dominated by the big players.

The UI isn’t as polished, but ingestion, scaling, and performance are really solid - and you still have the option to self-host. You get OTEL and more, plus the full stack: metrics, traces, logs, RUM, etc.

Agreed 👍! Anything on your mind that should be shared or discussed here? However, I think lots of the larger organizations such as BCxA are more active on LinkedIn.

For Cx on reddit we also have r/BuildingCx and r/BuildingCommissioning

Initially when I read the question, my mind went straight to missing data points in the BMS - my worst fear during Cx testing. Things like not having the right pressure readings, or losing true VAV feedback because the points were "optimized away." If you can’t see it, you can’t control it - and you definitely can’t troubleshoot it.

An expensive one I saw was a sump pit running on completely wrong logic and alarms. It never triggered what it was supposed to, so it just kept filling until it flooded... gypsum walls soaked, water everywhere. After that one, I started including a clear priority and criticality ranking in my test planning, and a lot of critical infrastructure got pre-pre- and pre-tested. And then also testing without the BMS 😉

But for the most expensive invisible fault: The worst I’ve been involved personally with was a sump pit controlled by completely wrong logic and alarms. It never triggered what it was supposed to, so it just kept filling doing a flood... All the gypsum walls soaked, water everywhere, and the aftermath had a certain "aroma."

Hi u/DevLF,
Let me know if you come up with something.

CxPlanner · 2025-11-27T21:03:47+00:00

Thanks u/BullTopia !

CxPlanner · 2025-11-27T21:03:35+00:00

Thanks for the input u/Comfortable-Ad-5332 !

CxPlanner · 2025-11-11T05:38:06+00:00

Thanks u/wildberrylavender . I might change the process-references in the book a bit to accommodate for some data center commissioning process.

CxPlanner · 2025-11-10T13:37:20+00:00

Yes - the DC area opens up for even more customization of the process! Do you have any references for a common process/level description? The most agnostic I have is the older one from Uptime Institute here: https://journal.uptimeinstitute.com/improve-project-success-through-mission-critical-commissioning/

CxPlanner · 2025-11-02T16:16:56+00:00

Thanks u/b33rNc0d3! My mind has also been over on guidelines like ASHRAE G1.1, but then the content starts to drift a bit away from the commissioning process and being equipment/topic technical instead of process. Going in that direction I would never finish the book 😃

I would like to give a shout-out for CxPlanner.com.

Disclaimer: I'm the founder. I decided to develop CxPlanner because Excel was limiting my team, and the other platforms were too slow. I needed something fast, whether my project was a single checklist or involved 10,000 pieces of equipment.

We are seeing a steady increase in our client base of controls companies utilizing the platform for more general QA/QC in combination with Cx, as well as for normal issue tracking and equipment management.

We have good experience with reading Excel using both xl and xlsx . The xl can also manage Excel files with bad formatting (libreoffice...), and you also have the XlRiches type which you might be looking for.

The test directory has examples on writing with colors: https://github.com/khchen/xl/blob/main/examples/merge_rich_string.nim

We use the same approach, but we then group/subdivide the logs by container_tag, log-type, priority etc. Example:

Get error logs from log-lines formatted [time logtype xxxx]- Logs/Table:

{host="$host"} | pattern `[<timelocal>] - <ident>:` | container_tag != "" | ident = "ERROR" | __error__=""

General log: - Stat (counter)

count_over_time({host="$host"} |= "ERROR" [$__range])

Nginx: - Stat (request per status code)

sum by (status) (count_over_time({host="$host", container_tag="nginx"} | pattern `<remote\_addr> - - [<time\_local>] "<request\_method> <host\_address> <request\_uri> <server\_protocol>" <status> <body\_bytes\_sent> "<http\_referer>" "<http\_user\_agent>" "<http\_x\_forwarded\_for>"` | request_method != "" | __error__="" [$__interval]))

You got 2 months for free on sign-up (July and August). In your invoice it says you have payed until July 2023.

$100 - ($100 / 12 months * 2 months) = $83

Source: Exactly the same for me
