Get MAX Heating Thermostat communicate every 30 minutes

[gdschut]

Hello!
I'm a beginning FHEM user (sorry, better english than german), my setup so far:
Raspberry Pi, Debian, FHEM
Homemade nanoCUL 868
2x Max! Heating Thermostat (Conrad)
Couple of DS18B20
I got it all working after a couple of days trial and error, google and find
My problem for now: I can not get the Thermostat give a regular reading. I have for example a reading at 1:00, than at 6:22, than at 6:48 and so on.
I would like to have a reading at every 30 minutes or something. Is this possible?
For the DS18B20 I ve set the attribute pollinginterval to get a reading every 5 minutes. But this attribute is not available at the Max device...
Does anybody have a solution for this?

Another problem is: sometimes I get a reading from Max without the temperature...:

My problem for now: I can not get the Thermostat give a regular reading. I have for example a reading at 1:00, than at 6:22, than at 6:48 and so on.

The reading is only sent if valveposition or desiredTemperature are changed
I am sure it's documented somewhere, possibly in the wiki

I would like to have a reading at every 30 minutes or something. Is this possible?

I believe http://www.fhemwiki.de/wiki/MAX!_Temperatur-Scanner can do this but I have no experience of it

Thank you!
I costed some work to figure things out, but now it is working as I wanted.
The Temperature Scanner makes this possible.
Thanks a lot!

Great that you have it working.
There is a lot about MAX and the way the system works in the early posts available here - mostly in German of course but http://www.domoticaforum.eu/viewforum.php?f=66&sid=f1db47236506b69262d83754c04ebfd7 is very useful too.
There are others online -  if youcan find them
