thanks @sgrayban for the reply. For some strange reason I cannot get the weather alerts to work on this 2nd Halo+ in Smarthings but yet they do on the 1st one which is not even on any hub now--just hardwired into mains after being removed from Iris. I'm about to just ditch this 2nd Halo+ as I have enough smoke detectors now & only wanted the weather alerts. Sure wish HE could support the weather features. Thanks again for the reply.
Don't toss the halo+ ! Keep it for a backup.
