So out of sheer curiosity I may have found a way to do this.
Apparently you can receive emails as an SMS on most major providers by sending the email to XXXXXXXXXX@CarrierSpecificAddress where the XXXXXXXXXX is your 10 digit mobile phone number.
i.e. the recipient email address would be something like:
1234567891@txt.att.net
See the following link to find your carrier address:
So using IFTTT linked to Wyze you can create an applet that sends an Email whenever the camera detects motion. Sending email via IFTTT is limited to 750 emails PER DAY which should be way more than enough if just using for Wyze notifications.
Seems like a decent failsafe if you have limited data or have an unreliable data connection.
I created a test applet to try it myself and will report back whenever I get some motion. I sent myself an email from a computer and the sms notification popped up on my phone pretty quick.
