 If your meter emits a layout not covered by the built-ins, you can register custom patterns. Lower priority numbers are evaluated first.
 ```c++
-parser.register_pattern("MyPattern", "TO, TV, S(TS, TU)", 5);
+parser.register_pattern("MyPattern", "TO, TV, S(TS, TU)", 5, {});
 
 // With default OBIS — used when the pattern captures no OBIS code
