Wyze Contact Sensors are tiny, resulting in short battery life and operational RF range. I would much rather have something that’s 2-10 times larger in size but with bigger battery and longer range. I had SimplySafe contact sensors and loved the fact that they run for years and RF range was many times greater than Wyze sensors, super reliable.
This has been implemented with the introduction of Sense V2:
