ETA on FLM v3

I'm just wondering if there is an ETA on the FLM v3?

free: extra fluksometer v1 + 2x 100A clamps

Howdy All -
I'm changing some stuff around at home and have an extra fluksometer v1 and two 100A clamps as a result. Free to a good home, just cover postage. Looks like the whole thing will fit in a USPS priority flat rate small box.

PM me if you want it.

RTFM - but where?

The pdf-version of the Fluksometer version 2 installation manual which was located in the Install section of this website seems gone.
But this does not provide an issue, as we can expect a new manual, especially for the FLM3E, to be published soon, can't we?
And for the FLMv2 there is the wiki/markdown version containing much more information than the previous pdf one, available at https://github.com/flukso/flm02/wiki
So, jump to the manual wiki, if you dare...

Upcoming FLM v3 - features, changes, points-of-interest

As presented in the status update and live at the grid:camp there is a new version of the Fluksometer visible on the horizon. (New Horizon?)
Even though I will just become an early adopter, there are some interesting differences to the current version 2 FLM notable right now:
Besides a more powerful processor there are "severe" changes in how the FLM detects current and voltage, enabling it to detect "all four quadrants of AC power flow" - this written, there are new current clamps and a special power supply provided with the FLMv3 essential to its operation.
With these hardware changes, there will also be a lot of software changes which I expect only very limited to be provided for the FLMv2 (even though handling seems quite similar, for example by interfacing sensors via the built-in MQTT broker).
An interesting feature thus taken from the source code are new MQTT topics reflecting the new features; beside the "well-known" /sensor/+/counter and /sensor/+/gauge there are distinct "flx" topics:

  • /device/+/flx/sar/+
  • /device/+/flx/sdadc/+
  • /device/+/flx/voltage/+
  • /device/+/flx/time

I would be eager to get to know some experiences of early adopters/beta testers to share here. This might help understanding to upgrade... (I will also work on a successor of local visualization on receiving my unit)

grid:camp follows elektro:camp

To all tinkerers and energy hackers there was another opportunity for a meet-up. Thanks to Roel, from Brussels 3E and the opengrid initiative, we took two days to discuss energy management, its visualization and some more topics. I wrote up a brief summary at https://energyhacks.wordpress.com/2016/04/25/brussels/ - Bart here also showed the new FLM03E and a kube in the wildlife (there are actually some deployments already). So, this as an appetizer to all Fluksonians out there...
(this put into the dev corner as being a starting point for surely new developments)
