I have followed the guide Adding clusters to Matter application to add two TemperatureMeasurement clusters to the Template sample.
I have flashed this onto an nRF52840-DK and hooked up a PPKII to the External Supply. I have switched SW6 to nRF ONLY to take the peripherals out of the equation.
The power consumption is a whopping 500µA even with CONFIG_SERIAL=n
In this post, Power consumption of Matter template example - Nordic Q&A - Nordic DevZone - Nordic DevZone, the user converts to from a Minimal Thread Device to a Sleepy End Device and has a tiny power consumption.
I have tried everything I could find to make mine sleepy, but nothing has worked so far.
Can you please provide me some guidance on making this work??
