Hi,
webtag "<#IsRaining>"
is it possible to change the output value "1" into the word "it´s raining" and the output value "0" into the word "it´s dry" ?
when it is possible, where I can find the values ?
Thank you for help.

You could do it JavaScript in the client browser, or in PHP if you use that server side.
Code: Select all
<script>document.write(<#IsRaining>==0 ? "it's dry" : "it's raining");</script>
pecked out on my phone!

I want post on my Homepage:
"it´s raining" or "it´s dry"
or can I use the rain-rate webtag?
for post:
"no rain"
"little rain"
"strong rain"
"very stron rain"
etc...
I can not php or Java, becaus I´m only a user.

Note that the <#IsRaining> web tag only works if you have an RG11 rain sensor (as mentioned in the wiki) and it is set to 'it's raining' mode (apologies if you knew this and do have an RG-11). Otherwise, you will need to use the rain rate, as you suggest. So, for a simple yes/no, you could use:
Code: Select all
<script>document.write(<#rrate>==0 ? "it's dry" : "it's raining");</script>
For a more complicated version with several outcomes, you would need to use an if/else if/... construct.

Code: Select all
<script>document.write(<#rrate>==0 ? "it's dry" : "it's raining");</script>
it don´t work, because if no rain, rrate are 0
,0
I tried to change the script into
Code: Select all
<script>document.write(<#rrate>==0,0 ? "it's dry" : "it's raining");</script>
but it doesen´t work ;-(
what must I do?
Thank you for help.

Ah, yes, good point. Javascript comparisons baffle me at times, and Javascript doesn't understand decimal commas. We really need Mark to give us the definitive answer, but this might work:
Code: Select all
<script>document.write('<#rrate>'==='0,0' ? "it's dry" : "it's raining");</script>

Yes, that will be OK in this case.
If you want a more general solution that will work with either dot or comma decimals I would use...
Code: Select all
<script>document.write('<#rrate>'.replace(',','.')==='0.0' ? "it's dry" : "it's raining");</script>
or even more generally (in case the decimal is dropped, or more decimal places are added, or IsRaining produces an unexpected string )...
Code: Select all
<script>document.write(parseFloat('0<#rrate>'.replace(',','.'))===0 ? "it's dry" : "it's raining");</script>

Try...
Code: Select all
if (parseFloat('0<#rrate>'.replace(',','.')) > 0) {document.write("it's raining");}

the Images are on my webspace (for example
http://www.webspaceXYZ.de/image-dry.jpg" and
http://www.webspaceXYZ.de/image-rain.jpg").
