Domoticz

Hello

Just noticed InfluxDB option has been added under Data push. How do I define user name and password for InfluxDB? as there is no option for that under General settings section.

Many Thanks

Excellent option, now I can see my data in Grafana finally. Something that did not work when using http-link.
I guess because of the timestamp... in '1970-01-01T00:24:47.358933Z' that problem is now over when using this option.

But maybe I did not read the documentation correctly with the time keywords. https://www.domoticz.com/wiki/HttpLink

Hi sincze.

How did you configure your connection settings? Did you create a new database without password in InfluxDB? or there is a way to include InfluxDB username and password from settings page? Could you send a screenshot of your InfluxDB connection please?

Thanks
Filip

Ok will provide screenshot ASAP. Moved back to http-link btw.
Creates more recognizable table names. Both work. At the moment I prefer http-link.

Please find attached my settings: Database was created in influx with:
CREATE DATABASE domoticz

if I remember correctly.

Hello,

If you have put a password to yout database (what I recommand)

In database field, put:
domoticz&u=DatabaseUser&p=DatabasePassword

and it works !

Yes that is correct

I've configured Influx Data push from Domoticz (More Options/DataPush) and had initial SUCCESS; verified data is being sent an received/queried by InfluxDB, but FAILED - no luck at all querying the data and getting charts in Grafana. Would greatly appreciate guidance from the pioneers before me, in particular examples of exact queries or suggestions re: Grafana.

Here's my setup:

Domoticz on RPi3 with sensors from MySensors, and ESP Easy, running reliably several months. I configured several sensors as a test in Influx Data Push, and successful eliminating config errors showing in Domoticz Logs. I can now see the Domoticz log showing all configured device info going out, example:
InfluxDB & Grafana Installed and configured on separate Linux (Ubuntu) box. Created 'domoticz' database in Influx. Configured data source in Grafana linked to 'domoticz' database successfully.

Failed to create any chart in Grafana that would display data values with hours of fiddling, although query editor was correctly seeing data fields like "Temperature", "Humidity" etc. Chart area always showed spinner with any query, Googling suggests a 'stuck' query.

Decided to fall back to confirm Influx was really getting the data, ran through the Influx docs and ran command line queries and got results confirming the data structure and devices were certainly there

">show series" included:
> select * from "Temperature" shows values are there... Yet in Grafana chart creation, although the relevant device names, etc are seen and selectable in the query, with a resulting query (among innumerable variants) like:
Set chart time range to past 5 years. Produces a blank chart and never-ending spinner in the upper right corner.

SO..... I i figure InfluxDB seems to be working and have the data, and thought maybe my Grafana install was botched, so I installed another instance of Grafana, from scratch, on a rPi3 and connected it to the same Influx database... No problem connecting to database. Same spinner, no data displayed.

Opinions?
Am I botching this query in Grafana?
Is something wrong with my Grafana config?
Is the spinner always there with any graph query in Grafana that produces no data?
Is there something wrong with the "time" data shown in the InfluxDB command line query above?

Any ideas greatly appreciated.

Thanks, Tim

If the data is in Influx try the data in grafana not 5 years back but back to the year 1970. I had a similar issue of data not showing up.

Great tip! Digging into the database sure looks like timestamps aren't right.

I'll look at my configs...do you recall how you fixed it?

Thanks, Tim

ADDENDUM: Spent may hours looking for workarounds, created entirely new database and messed with every possible variant. I'm fairly certain that the InfluxDB Data Push is simply broken and loads all data except with broken timestamps, making them useless.

Just to be sure. were you using HTTP link or INFLUXDB under DATAPUSH menu??
These are my settings.

I have been using "influxDB"

I am getting correct sensor values, and have experimented with tacking on 'precision' options to the DOmoticz InfluxDB push page, but still stuck in 1970.

mmm that one worked for me. can you switch for a test to httplink and add the line a shown in my earlier post??

I MOVED away from both http link and influxdb from within domoticz as I received error messages like 'to many open files'.... causing domoticz to lock up. Had to solve it in a different way. (Pass2Php with custom influxdb function). Has been running fine since then

sincze, httplink is pushing, no errors in log, but I can't figure out how to get remotely similar data in the httplink config or any values. Most of the wiki and older posts seems to be from old version of InfluxDB,

General settings as you suggested adjusted for my ip.

Data:
device_%V value=%v %t1 %n %D Tried lots of variants...including what you sent. Syntax is unclear to me with commas, spaces, etc varying widely in examples I'm finding on posts
active and debug checked

Edit Link:
Target Type: Global variable (errors when I try Virtual Device)
Device name from popup for items.
Value to sent: no choice here
Target Variable: No idea what goes here, generic terms like "temp"
Include link checked
Link active checked

I'm not getting any values in Influx that I can pick out with queries

I think I'm probably going to have to give up on this unless the InfluxDB option gets fixed...too much time wasted on this in last several days. So close with that, just broken timestamps I can't fix.

Tim

mm this should work.

Correction of correction! I'm not having success with HTTP push, the data posted below yesterday is definitely from the InfluxDB push, I had the wrong database in use. But I have not spent much time trying to get the data configured correctly.
----------

Correction - with the HTTP Data Push config listed just above, I AM getting values and seeing name and tags....but the dates are as I reported before:

Code: Select all

> select "value" from "Temperature"
name: Temperature

I seriously wonder if part of the problem here is related in some way to how InfluxDB assigns schema and data types based on the first data in to the file? I wonder if the code verification is challenging unless its done with a virgin empty database? I simply created a series of new database files as I went along with my trial-and-error as it appeared that behavior sometimes changed when I did this.

But what do I know.
