Can I get webserver to show a temperature graph?

[Pallantir]

I have a bunch of temperature sensors, in almost every room in the house and the cabin, and I would like to be able to see in the webserver page how the temperature has changed over time on a few of them (mainly outdoors and indoors at the cabin when we're not there). At the moment the server shows the current temperature, but I have no idea how to creat a graph for this. Is there any code anywhere that can help me do that?

There are several ways doing this. I personally use SwitchKing (SK) in a test drive since a while.

I have configured a data source in SK for each sensor of interest. Then I am using the SwitchKing plugin for EG to send data via the REST interface.

Below is a picture from SK showing one of my sensors ( a modified one for measuring the light level). Also below, see some screens as well as the python script from my EG configuration.

Below, configuring the SwitchKing plugin for EG

Define a macro that captures the event and evaluate, format and send to SK

The script

Code: Select all

def eventHandler(base, pload):
    try:
        if str(base).find('THGN122/123, THGN132, THGR122/228/238/268 id: 7940') > -1 :
            m = str(pload).split(' ')
            h = str(m[6])
            #print h
            eg.plugins.SwitchkingTellStick.DSSet(u'', u'Ljussensor', h, 0)

    except:
        pass


eg.event.suffix_copy = eg.event.suffix
eg.event.payload_copy = eg.event.payload

eventHandler(eg.event.suffix_copy, eg.event.payload_copy)

Thank you very much! I'm going to play with this in the weekend.
