 * lgk fix issue in porting where configure caused error, also add checkin clear and last status 12/21
 * also add gas as well as smoke attribute, and attributes for zonetype enrollment model etc.
 * also add multiple fingerprints.
 *
 * lgk v 3 
 * add user defined checkin time. in seconds 120-86400 (1 day) cannot go less than 2 minutes/120 or it doesnt work.
 * also add debuging 
 * 
 * ;gk b4 remove gas and change to naturalGas add capability gas detector.
 * lgk 9/22 as istatechange = true to force a clear status to always go in the log.. otherwise when hit refresh nothing
 * but battery events go in.
