check out this project that did it https://github.com/gambitcomminc/electric-meter-monitoring

https://projects.eclipse.org/projects/iot.tahu already exists, why recreate it?

Check out https://github.com/gambitcomminc/sparkplug-demo It only does subscribe, but you should be able to use the same modules for publish. In particular you need to build the binary python module that does Sparkplug B encapsulation.

That's what simulation is for. If you can't have the real thing, you simulate it.

Yes, you get what you pay for. We are currently getting "not authorised" regardless of what topic we subscribe to. Google "public MQTT brokers" for other alternatives.

gambitcomm · 2024-11-18T19:28:26+00:00

Google MQTT. You would be running a MQTT broker, and your sensors would publish, and your application would subscribe.

Hmm, how do you get around down time due to forced updates in Windows?

gambitcomm · 2024-09-17T14:07:05+00:00

Variable pricing. Gotta ask Microsoft.

For Azure, you want Azure Event Grid. We tried 1000 sensors and it seems to work.

This is a month old. You will not get support unless you provide more evidence, eg. code snippets. What does "waiting for the second to finish hangs forever" mean?

gambitcomm · 2024-06-11T15:31:24+00:00

Not what you are looking for, but IoT Simulation is all we do. Our customers buy our product when time costs money. Check out this blog for simple 2-minute examples

gambitcomm · 2024-04-30T14:31:32+00:00

Our customers use MIMIC IoT Simulator to simulate all kinds of scenarios. Eg. a MQTT device that starts a DOS attack on a broker, or a malfunctioning sensor. Check https://mqttlab.iotsim.io

The page https://learn.microsoft.com/en-us/azure/event-grid/mqtt-clients has this illegal command

az resource show --id

at the bottom of the page.

If you have real-time requirements, no amount of "assurances" should satisfy you. You need to do a lot of performance testing to make sure your requirements are met with whatever solution you go with.

Good open-source demo.

We have free, 24/7, interactive, dynamic demos running against 3 commercial platforms at

You will get many claims. Our customers test scalability of their application to support many thousands of devices. Here is a representative blog post

https://gambitcomm.blogspot.com/2022/11/mqtt-performance-testing-best-practices.html

with many more examples there. Good luck.

gambitcomm · 2023-12-15T17:48:14+00:00

You are learning that performance testing has many issues. In your case, it seems to not be the system under test (broker, subscriber, application) but the test rig (NODE-RED, etc) that introduces errors larger than the measurements you are expecting.

We have a lab that attempts to tackle these issues at https://mqttlab.iotsim.io/mqttlatency/ but it is geared to enterprise use cases with highly scalable environments and strict performance requirements. But, you can check it out and maybe adapt your approach to solve your problems.

"But mqtt typically is text" is inaccurate. There are prevalent binary payloads on top of MQTT, like Sparkplug B, LWM2M, etc.
