Good for basic lighting
Our company installs Alliance transformers, and we use the WiFi smart plug to expand capabilities as the Bluetooth transformers have such a short range. In my experience, this is a reliable app for clients with a reliable WiFi connection and one or two transformers. Our clients typically set their lighting once and then rarely make changes since there is already a built in astronomical clock to adjust for seasonal daylight hours - if you’re wanting to make frequent changes, you’ll probably find that you need to refresh the WiFi from time to time to reestablish connection. That can cause some frustration, and I hope the developer is working on a fix.
