In an old post I saw PLEG was not supported under AltUI, is this still the case? I cant get it to work on my new Vera Plus and AltUI.

Afraid It is still the case. The plugin is too sophisticated and encrypted.Some serious work would be needed. Alternatively you can investigate the rule plug in of @vosmont which seems quite powerful and has a dedicated user interface for altUI.

Thank you, RulesEngine works and looks very promising.
