Do you have an OpenSprinkler 3.x? (i.e. 3.0 3.1 or 3.2)? If so, you can upgrade your firmware to 2.2.0(2) and use OTC token. It goes through the secure server https://cloud.openthings.io for remote access.
With this method, authentication and use of the application will be secure?
I’ve already configured this token, but I didn’t think it was enough.
Thanks a lot.
I’m going to order a second programmer for my parents 🙂
