@taxfromdk difficult to change the battery. probably to cause damage. so don't do that

Thanks for the info. Solves the issue. So looking at the schematic I would connect to pin 28 for 5V and pin 1,3 or 5 for GND. Cheers.

@rhannink This looks good! I'm looking for a replacement of the Zipato Mini RFID tag reader I've been using the arm/disarm my Home Assistant alarm system. Unfortunately these are sold out everywhere. Your project sounds very interesting but at the location I'm planning to put this, there is no power... Would you think it would be possible to have the entire project (controller + RFID reader + screen) in deep sleep most of the time, and only wake it up when one of the physical buttons is pressed? Is there an estimate about how much power that would still use? Thanks in advance for any reply!

Very Nice

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 !!!

Yes, you must replace for example read temperature block with block which reads temperature from hat you use. Ewentually adds new block lcd.print for printing pressure and humidity with appropriate blocks reading data from these sensors But problems may be with icon and weather description, because the weather description and icon number corresponding to the current weather is downloaded from the accuweather.com website. some fun and testing with font type, coordinates and colors and it will work

Very nice, look forward to the full writeup

Great project
