Hello fpaliuc, are you using emoncms.org or your own instance? For the PIR it might be better to use PHPTimeSeries or MYSQL rather than Timestore, given that it isnt regular. If you have your own installation of emoncms you could switch the feed creation mode to mysql or phptimeseries temporarily to do this (in settings.php).

You could then use:

feed/list.json to get a list of feeds with their last values.

Hello TrystanLea!

Thanks for your answer. Yes, I'll use my own instance on a RaspberryPi. I understand that I could switch the feed creation mode to MySQL or phptimeseries but, is it possible to do this only for the PIR feed and let the others set to timeseries?

Practically Arduino pushes the sensor's values every 10 seconds. The value of the PIR sensor is sent only when it changes from 0 to 1.

Thanks again

Yes, just create your timeseries feeds with:

$default_engine = Engine::TIMESTORE;

then switch the settings to

$default_engine = Engine::MYSQL;

or

$default_engine = Engine::PHPTIMESERIES;

and it will create feeds in those engines.

Then switch back to timestore after your done creating the feeds.

I got it. Thank you very much!!!

The only thing I need to understand is how to get the latest values?

I'll have 3 feeds set as timestore and 1 as MySQL. I'll have to get the last value for each feed in order to use them in another .php script.
