I purchased the RTU5015 purely because it stated iOS app iOS supported.
At first things looked good, however things soon went down hill fast.
The RTU5015 works only with SMS, this app states Compatible with iPhone (sends sms)
IPad and iPod touch (do not send sms)
When ever you try to send a command it opens iMessage to send that command and of course you end up with "error iMessage not sent"
The only way to get this working is on a iPhone turn data off and select send message as sms.
Avoid seller Mary Liu she is refusing refund and exceptionally rude.
