Is there anyway within the rules engine to parse a string in an attribute/variable?
I see on HTTP actions there are some options. But when just working with variables/attributes I don’t see anything.
I don’t think custom tiles gives you access to devices/etc the js library.
Hi @Edward_Brown, string functions, like CONTAINS, START_WITH, END_WIDTH, INDEX and etc, are not currently supported, but you may be interested to cast your vote in the following feature request and describe your use case(s) in the comment to help boost the priority.
