How to mask a point in a path?

General
1

I have a particle sensor under tasmota.... I get the payload in the format

Payload:{"Time":"2021-12-06T10:53:53","BME280":{"Temperature":22.3,"Humidity":38.2,"DewPoint":7.4,"Pressure":997.8},"VINDRIKTNING":{"PM1":895,"PM2.5":8,"PM10":33},"PressureUnit":"hPa","TempUnit":"C"}

...
$string(VINDRIKTNING.PM1) works
$string(VINDRIKTNING.PM2.5) does not work
$string(VINDRIKTNING.PM10) work
...

How can I mask the dot at 2.5?

Feed your payload trough a json node and everything is handled for you, no need to works with strings.

You need to use the alternate syntax VINDRIKTNING["PM2.5"] instead

works perfectly

Thanks a lot guys!

PS.:
Does not work after all... the node does not complain, but the output value is wrong...

however,

$string(VINDRIKTNING."PM2.5")

Works as desired.

Thanks...
