v246: Updated FLM local visualization

by gebhardm on

Taking advantage of the new firmware version 2.4.6 I had to perform some minor changes to the FLM local visualization beyond the "basic real-time logging of MQTT sensor topics". By using my FLM local chart, gauge, graph, and panel display it is also possible on this update to visualize sensor readings in a "more graphic fashion" directly from a local Fluksometer, including a retrieval capability for the newly introduced TMPO persistence.
Feedback welcome - a pull request into the original flm-ui is set, so let's see whether Bart will include this into a forthcoming update.

watthour of the night

by hanskraayeveld on

I think the watthours of the night isn't right. The watts are good, but the watthours are measured if the night is 24 hours long...
And in the Netherlands, that's not gonna happen...

Second...
I like to see how much kWh my pv has produced. If I want to check it I have to go to day, wh cumulative and the highest value minus the flat line of the graphic (the night) and than I know.
Is there not an option to start the day at 0.00? So a realy DAY cumulative, and not a 24 hour cumulative?

Thanks.

Voltage measurement

by rayellam on

Hi All,
My first post here. This device looks interesting but i cannot find any reference to how the AC voltage is measured?

P(apparent power) = Vrms X Irms

So does this mean the power calculated is approximated based on a "plug-in" value of volts via software? can the unit calculate power factor and real power?

Thanks
Ray

Help request for Gebhard Combined script

by vk2him on

Hi Gebhard,

I've been playing with your excellent mqtt scripts trying to get the combined to work from https://github.com/gebhardm/flmdisplay , but with no luck.

I have the following displayed when starting the node:

  1. www:combined vk2him$ node serve_flmdata.js
  2. Database flm successfully connected
  3. Detected MQTT service on: 192.168.1.73:1883
  4. Create/connect to config table successful...
  5. Create/connect to data table successful...

However when I navigate to localhost:1080 I get the following displayed

  1. Latest MQTT message: no message received

The mysql table is also empty.

I can connect fine with mosquito with no problem as you can see:

  1. www:combined vk2him$ mosquitto_sub -h 192.168.1.73 -p 1883 -v -t /sensor/#
  2. /sensor/c7c90d029e018769b5fb26380c369845/counter [1428230773,924264,"Wh"]
  3. /sensor/c7c90d029e018769b5fb26380c369845/gauge [1428230775,590,"W"]
  4. /sensor/c7c90d029e018769b5fb26380c369845/gauge [1428230776,586,"W"]
  5. /sensor/c7c90d029e018769b5fb26380c369845/gauge [1428230777,596,"W"]
  6. /sensor/c7c90d029e018769b5fb26380c369845/gauge [1428230778,588,"W"]
  7. /sensor/c7c90d029e018769b5fb26380c369845/counter [1428230779,924265,"Wh"]

As well as the latest versions, I have even tried installing an older 0.9 version of socket.io but it fails too:

  1. npm install socket.io@"~0.9.1"

I have tried your other older scripts by using the 0.9 version of socket.io but I always get this:

  1. Latest MQTT message: no message received

So I was wondering if I have done something wrong, or if my FLM needs something else to make it work? I am running Version 2.32

Thanks
Ian

Zigbee signals from Enecsys gateway

by voogt on

Will Flukso work with Zigbee, especially a Enecsys gateway. Enecsys a brand with very good micro inverters for solar energy went bankrupt so online monitoring will probably stop?
