M5Stack controllers are all still supported and while batteries do die if not looked after (I have a few that need replacing) the batteries are noting special and can be found for a few dollars/pounds. Unfortunately Battery monitoring was only added to later models and the grove connector is NOT connected to the battery as it runs at 5V through a boost circuit. without writing a program the best way to check battery voltage is to open up the device and test the battery voltage with a multimeter.

Please email support@m5stack.com to get a replacement

Hi @Happy-Hippo It is true that the bmp280 and dht12 do tend to have their readings thrown off a little by the M5StickC's internal temperature, which was a bit of an oversight on M5Stack's part. Perhaps adding a layer of insulating material between the stick and the yun might solve it. I cant see how the atmospheric pressure should be so adversely affected though. I'd imagine going with an mqtt platform such as thingspeak or iftt would be the best way to get the weather data to your stick C but I haven't personally tried it. Great idea to pacify your wife, let's see if it works :p

@happy-hippo No issues taken mate. No Independent writer. I started writing my own documentation as a way to understand the products but its grown quite big now (209 pages just for UIFlow!) so I know the frustration.

@happy-hippo The tof units have a regulator that converts the 5v down to 3.3v

@happy-hippo Correct. In order to connect more you need to use the PbHub. As you have discovered, sensors use 1 pin and actuators use the other pin.

Hi @Happy-Hippo if you press the pogo pins do they spring back fully? or get lodged? usually there is a bit of a gap but it shouldn't affect normal operation

@m5stack Many thanks for the quick help. With the spare part the BALA now works perfectly!

@happy-hippo I have the port pin listing here https://github.com/Ajb2k3/UIFlowHandbook/blob/master/UIHB1404192.pdf but you will need to check out the official micropython forum for the ssd1306

@happy-hippo Music is not properly implemented in UIFlow and the walkaround for it is a bit complicated. but in essence I had to create variable for beats and DPM and then tie them all together. Unfortunately I seam to have misplaced the timing demo.

ENVII HAT on M5StickC works with the example by changing: Wire.begin(32, 33); to: Wire.begin(0,26);
