How use TempChangeLastDay ?

[Areecki]

Hello
I added new tags on the website, but I would love to have another one.
Currently I have the following: #temp>, <# RecentOutsideTemp d = 1>, <# TempChangeLastHour>, # temptrend>, <# avgtemp>, # RecentOutsideTemp d = 7>.
I miss the mark "change in temperature for the last day. More specifically, the temperature difference between the current temperature and the temperature of which was 24h00m00s ago. That is something on the principle of operation of the <#TempChangeLastHour> only <#TempChangeLastDay>. Is there such a tag? Is it possible to write on an equation of the type: <#temp> - <# RecentOutsideTemp d = 1> = <#TempChangeLastDay>?

You could do that with a bit of JavaScript. Something like

<script>document.write(<#temp> - <#RecentOutsideTemp d=1>)</script>

[Areecki]

Like that ?

Yes, but actually you might need some rounding:

<script>document.write((<#temp> - <#RecentOutsideTemp d=1>).toFixed(1))</script>

Now I have : http://scr.hu/0fqx/j2yrm
But temp now is -2,7 C , last24 h = +0,2
Script announced on the website 2,0 C and I would like to count the exact changes or -2.9 C (0.2 - (-2.7) = -2.9 C.
Script work like that ---> http://scr.hu/0fqx/p85p5

Do you use commas for decimals? If so, you'll need

<script>document.write((<#RCtemp> - <#RCRecentOutsideTemp d=1>).toFixed(1))</script>

[Areecki]

Commas appear on the site and program.
Okay I'll try.

[steve]

You might find that the result comes out with a decimal point rather than a comma. There are probably ways around that, but I don't know what they are.

IT WORKS !!!

OMG, thank you very much it works.
Created tag: Change of temperature for the last 24.
In this way you can create a change is not only 1 but any other.
Just use #temp> and #RecentOutsideTemp "x" = "y">

Thought about to add a tag: Temperature year ago? So that displayed a temperature of 16:00 28.XI.2013?

[steve]

To change the decimal point to a comma, this might work:

<script>document.write((<#RCtemp> - <#RCRecentOutsideTemp d=1>).toFixed(1).toString().replace('.',','))</script>

[Areecki]

I do not need to change the decimal point. Such data are right for me, but they can be useful to someone else.
1. Is it possible to somehow pull the temperature that was a year ago at the same time?
2. Is it possible to semehow pull the change temperetaure in the last 10 minutes or 30 minutes ?

1. Is it possible to somehow pull the temperature that was a year ago at the same time?

No, because it would require the storing in memory of a lot of values (all of the values for the last year). Otherwise it would have to start searching through the log file for a year ago, and that would be very inefficient and slow. It really needs the data to be in a proper database rather than flat files, so the values can be extracted efficiently.

2. Is it possible to semehow pull the change temperetaure in the last 10 minutes or 30 minutes ?

Do the same as you did for a day ago, but instead of d=1 use m=10 or m=30?

[Areecki]

1. OK
2. : <script>document.write((<#RCtemp> - <#RCRecentOutsideTemp m=30>).toFixed(1))</script>
But must I have in the web display to RecentOutsideTemp m=30 ? or only script ?

[steve]

You just need it in that script.

[Areecki]

Yea !

<script>document.write((<#RCtemp> - <#RCRecentOutsideTemp m=30>).toFixed(1))</script> or m=10 or d=2 or another ; )
