Lazy self-care fish tank control system

The lazy self-care fish tank control system is mainly aimed at fish farming enthusiasts. As long as you use your mobile phone through BLE, you can manually control the start, stop, and feeding of the fish tank's electrical appliances. At the same time, the real-time time, supplementary lighting time, automatic feeding time, water temperature monitoring and alarm, etc. can be set through the APP at once. Enthusiasts are only responsible for watching and appreciating the fish, and the other things are left to the control system!

Weather forecast on the mobile app? Weather warning text message? It can only be regarded as a late report. I am lazy, do it myself, have enough food and clothing...
