Hi, i have a esp32 which has a server running and it monitors my bbq at home for temp and liquid level. Im having trouble getting it to send notifications so decided to try a simple app. This is the page, its a simple page but can get the code working so it can communicate on the phone. this is the page . Ideally i will set the esp32 to be in bluetooth mode if not connected to local wifi, so then the app can connect to bluetooth and i can set the wifi to local, then the bluetooth will turn off and it will then use the wifi. The app itself is 4 notifications. 1. Temp Ready. 2. Temp high., 3. Temp low. 4. Liquid level full. Its very simple and easy but just need to know how to get it to communicate to my esp32. etc. thanks
