Couple of Newbie questions

[gazza_d]

Hi - Couple of newbie questions.

1. I have an open energy monitor , and have knocked up a shell script to read the current value and put it into a shell device variable. I have also added the shell device to the Energy and Power groups. I can see the value on the energy tab, but cannot get it onto the home screen. I mustbe missing something, but cannot see what. any ideas?

2. Is there any support or workaround to support Tellsticks? I saw someone was developing a plugin a while ago, but it seems to have come to nothing,

thanks

Gary

Gary,

put your device in groups Energy and Power, and for some reason Value2 of the device must be filled.
I think this comes from the first power measurement device I had the RFXMeter, should make it more generic.
Are you willing to post or e-mail me the script and some info about your open energy monitor setup, so I can put it on the wiki?

I have a Tellstick laying around, wanted to code a module for it, but it's performance is not that good, so haven't started it.
I guess you can use it somewhat with the linux library and some shell scripts and calls from event actions.

Thanks, that fixed it!. Manually dumping a dummy voltage value for now.

Feel free to post the script on the wiki or use it. It's not fancy. Just dumps a web page with the current power vaule to a temporary file, and then parse out the actual value using sed.

Code: Select all

#!/bin/bash
lynx -dump "http://server/emoncms3/feed/value?id=13&apikey=**your_emoncms_api_key_here" >feed.txt
echo 230
sed -n 4p feed.txt | sed -e 's/^[ \t]*//'

I'll have a play with the shell scripts for the Tellstick. I only a have a fairly small house so haven't experienced the range issues others have reported.

Regards
