Page Regex Match multiple values

[PCoDev]

Hi,

I have the following data published by a web page:

T1|25.60
T2|25.80
T3|25.80
T4|25.80
H1|35.80
H2|34.00
H3|35.20
H4|36.80

Where T stands for temperature and H for humidity. The following regex matches all values I need to check:

Temperature: T\d\|(.*)
Humidity: H\d\|(.*)
All: [TH]\d\|(.*)

I'm trying to create a web.page.regexp item to check for the values above.
The goal would be to define a trigger for all T values and all H values and have a graph showing these.

Unfortunately, I have problems reading the values:

This works fine:
zabbix_agentd.exe -t 'web.page.regexp[192.168.3.133,index.html,8080,T\\d\\|(.*),,\1]'

But as soon as I try to get the second group it just returns an empty string.
Doesn't work:
zabbix_agentd.exe -t 'web.page.regexp[192.168.3.133,index.html,8080,T\\d\\|(.*),,\2]'

Any Ideas why this doesn't work?
Also will this be doable by a single item or would I need items for T and H or even an item per value?

Thanks in advance!
