Hello @JackStewart,
There are plans to develop a new WebUI for Ezlo controllers. Right now, the project is in the beta phase. More information can be found here.
In the meantime, you can manage your scripts using the API. Please check this article.
Finally, your controller should be accessible through the VeraMobile app all the time. If you are experiencing any issue with the access, please send us an email at support@ezlo.com.
