Hi , I used your application before I discovered the M5stack. It was on a fb page for diabetes and nightscout and a fb member was so kind to burn It and adjust the parameters for me. It is an excellent application, thank you ! And now I am discovering myself the m5stack...what an incredible device and There are realy endless possibilities... Maybe Considering things or features to add In future : dark screen and not displaying the value until a button is pressed... need full darkness to sleep a feed with mqtt to connect to alexa and be able to ask the bg level to alexa When m5stack is on (i used it with Smartnest.cz to connect my ENV hat and am able to ask alexa the temperature of poolwater ) Good work anyway and thank you a lot !!!
