THS-M6 BTHome firmware has an expected lifespan of over 3 years, simple access, timely updates, we love this stuff.

With the current test, we think that in broadcast mode, and the default update detection (1 second), the leveling current is within 13uA, and a standard CR2450 battery assumed to be 550mAh, then the ideal operating time is 4.8 years, while in reality, counting the various circumstances discounted, it has a chance to be closer to 3 years.

That's a fantastic result!

thx the great work of pvvx.
