Summer break

We've got a summer break scheduled from July 8 till July 31. All outstanding orders will be shipped today. We will resume shipping of new orders on August 1.

An overdue status update

You may have noticed that the Fluksometer v2 and its matching current clamps have been removed from the web shop. Does this mean we will not be selling Fluksometers anymore? Not at all. For the past nine months, we've been diligently working on the development of a worthy successor to the FLM02. The device will be called the Fluksometer v3. No surprises there. The FLM03 has entered pre-production as of late last month. We're expecting this first batch by the end of March. In the mean time there's still a sizable amount of code that has to be written, primarily for the new Cortex M4F microcontroller.

As for the Fluksokube, a.k.a. FLK01, it's definitely past the 'paperware' status as can be seen in the picture below. Half a dozen Kubes were deployed at Flukso HQ in August 2015. All of them are still reporting temp, humidity, pressure, light intensity, vibration and battery readings on their first Lithium battery.


Both the FLM03 and FLK01 will require decent documentation. The Fluksometer v2 had a manual written in Latex. Latex is a great tool for typesetting, but not very well suited for documenting a continuously evolving product. There's a ton of information on the Fluksometer v2 buried in the forums that never found its way back into the manual. I think we might significantly improve in this aspect by using a publishing tool like Gitbook which allows for collaborative editing with Git(hub) as a backend. Does anyone have any experience with Gitbook? If you have other suggestions, feel free to comment.

Summer break

Flukso HQ is powering down from Aug 1 till Aug 15 for a well-deserved summer break. We'll be shipping again from Aug 17 onwards.

R247 bugfix release

This release fixes two bugs:

  • 3aab57 solves an incorrect sensor configuration in the tmpo daemon. No tmpo blocks will be generated in r246 without the fix.
  • 48d710 ensures proper arrow rendering on the local Kube configuration page.

If you've upgraded your FLM to r246 this week, please bump it to r247.

A big thanks to Markus for his QA work on this one.

R246 release notes

This latest FLM02 release has been in the pipeline for quite a while, but for good reason. The highlights of this release include initial support for the FluksoKube, the upcoming battery-powered sensor node, as well as a new time series storage format called Tmpo. Both topics were introduced at EC1404, the latest elektro-camp to date, see the respective presentations here and here. Once you upgrade your FLM to this r24x firmware, it will start logging your sensor readings in Tmpo format in parallel to the existing data path. Sensor data will still be available via the existing API in the 'old' format as well.

Both the Kube and Tmpo functionality will be described in more detail in future blog posts. Further improvements included in this release:

  • A heartbeat LED that can be reconfigured to signal the current logic level on pulse port 4 or 5. This helps in calibrating the FLS04 opto-reflective sensor, to be added to the Flukso web shop shortly.
  • Support for the DSMR4.0 Dutch smart meter standard. You can now select between the 2.2 and 4.0 protocol in the local FLM UI.
  • A 5ms pulse masking on pulse ports suppressing any spurious transitions.
  • A basic real-time logging of MQTT sensor topics in the UI using the Paho MQTT/Websockets JS library.
  • Logging of fractional counter values, which fixes the r232 known issue of real-time readings not being correct for pulse inputs with meter constants that are is not an integer fraction.

If you have a Fluksometer serial in the FL02xxxxxx or FL03xxxxxx range, you can now upgrade your FLM via a simple click on the settings (cogwheels in the top right corner) > devices page. The actual upgrade will take place on the next hourly FLM heartbeat. Make sure to keep your FLM humming during a scheduled upgrade.
