[Solved] pimatic-log-reader: how to continue...

---

log-reader

I try to read data with the pimatic-log-reader (see example https://github.com/pimatic/pimatic-log-reader#gather-temperature-values-from-a-log-file).

This is the config.json content about this:

-“plugins”:

{
  "plugin": "log-reader"
}

“devices”:

{
  "id": "temperature-from-logfile",
  "name": "Temperature",
  "class": "LogWatcher",
  "file": "/usr/local/pimatic-app/iobox/pimatic-setpoints.txt",
  "attributes": [
    {
      "name": "temperature",
      "type": "number",
      "unit": "°C"
    }
  ],
  "lines": [
    {
      "match": "temperature: (.+)",
      "temperature": "$1"
    }
  ]
}

The log file pimatic-setpoints.txt have two lines:

temperature: 21.1
temperature: 22.2

There are a new variable: $temperature-from-logfile.temperature but is always 0ºC.

Now, I don’t know how is the next step.

• When does it read?
  Which is the interval?
  Where is it configured?

I think the plugin need a new rule and I tried this:

{
  "id": "test",
  "name": "test",
  "rule": "if $temperature-from-logfile.temperature changes then $pot1k = 0",
  "active": true,
  "logging": true
}

but the pimatic is malfunctions (100% cpu, does not update sensors, etc.).

Works again when disable the rule.

Thanks for your help.

the logreader device will be updated when you are updating your logfile.
how and how often do you write your log?

I want to use a file with setpoints, i.e. setpoint temperature.
I write that on my dropbox.
Then raspberry pi cron reads the file every 5 minutes.
Normally the file don’t change for days.

I don’t understand. If device will be updated when file change, why is always 0°C ?

Works!!!

The problem was the last CR LF.

nice to hear!
will mark as solved
