As for case codes, C24 should be 1206 and C25 should be 0603 (both in inch)1. They are in parallel, which means that you just need to add a capacitor to one of them. However, since dozens or hundreds of uF is a huge capacitance, 1206 would be cheaper.

Что касается кодов корпуса, C24 должен быть 1206, а C25 должен быть 0603 (оба в дюймах)1. Они параллельны, а это значит, что нужно просто добавить конденсатор к одному из них. Однако, поскольку десятки или сотни мкФ — это огромная емкость, 1206 будет дешевле.

Getting the MAC of your Thermometer:

On boot the custom firmware will show the last three bytes of the MAC Address in the humidity display part on the LCD for 2 seconds each, the first three bytes are always the same (A4:C1:38) so not shown. Also the BLE name will include the last three bytes of the MAC Address.
