No Refresh possible

[pacman13]

Hi, first of all, thanks for this module. I will use it to receive over my local network XML data (status variables from my smart home environment). The module receives the data so it works so far. Now I try to refresh the data anyhow but I will not be refreshed. I tried now several options and also reinstalled the module twice ... other modules on my mirror like Traffic or Weather will be refreshed accordingly so I'm nearly sure that I missed some settings or steps to implement this module properly .. do you have any hint for me, from other installations maybe, why the refresh is not working? Thanks so far !
