However looking at logs, I notice the location event value is correct, but the description is wrong - it references a motion sensor. That motion sensor is indeed part of the list of sensors tracked by HSM when Armed-Away.

Could there be some mixup between lastEvt(Name/Value) and waterEvt(Name/Value) when sending the location event ?
