Happy to hear you’ve been using Ubidots. We don’t have this feature embedded in our platform since every device has a different way of doing OTA updates and remote management. We do work with our customers to add the custom functionality so they can do this from their Ubidots-for-business interface. See these examples of a device management interface and where the OTA button could go:
Our business licence also includes a user management interface to assign permissions. Let us know if you’d like to be contacted by our sales team for a call.
