Convert multiple rows to column (unpivot)

I am attempting to convert table1 to the output shown in table two. Is there a way to use multiple unpivot to accomplish this without skewing the data. Not sure what I'm missing but I'm getting 4 entries for each readdatetme.

I also tried grouping to no avail.

SELECT METERNUM
,SMREADDATE
,SMREADAMOUNT
FROM SMARTMETER A
UNPIVOT
(
    SMREADDATE
    FOR READDATE IN (READDATETME1,READDATETME2) 
) B
UNPIVOT
(
    SMREADAMOUNT
    FOR READAMOUNT IN (READAMOUNT1,READAMOUNT2) 

) C 

SMARTMETER

T2

CROSS APPLY can be used as a makeshift multi-UNPIVOT:

SELECT s.METERNUM, x.READDATETME, x.READAMOUNT
FROM SMARTMETER AS s
CROSS APPLY 
  (
    VALUES(READDATETME1, READAMOUNT1),
          (READDATETME2, READAMOUNT2)
  ) AS x(READDATETME, READAMOUNT)
ORDER BY s.METERNUM, x.READDATETME;

Results:

• fiddle

Also really annoying for READDATETME to be missing an I, for what it's worth.
