We are sorry for the trouble you experienced. There were connectivity issues for some users when the product launched, or shortly thereafter. I experienced them myself. But they were resolved with a firmware update. We changed the setup process so now you connect with Bluetooth before switching over to WiFi. It's been smooth sailing ever since. Well, mostly. Users that bought a unit with the old firmware may still have had issues until they updated the app. We've turned over inventory a couple of times, so I imagine most stores have only controllers with newer firmware. We update the app pretty frequently. One of the many reasons we built HYDROS is because CoralVue takes the heat if the app for a product we distribute is giving users issues. Now we control the app and when issues are reported, we can resolve them quickly. Our development team is all in-house and in the USA. There's new updates coming to the app that we'll be teasing soon. We are excited to show people how much HYDROS has developed!
