I’ve used YoLink temperature sensors for a couple of years now. They have indoor-only sensors (typically with a display,) outdoor weather-proof sensors with no display, leak sensors, etc. Very long range. Requires a device hub. It will send alerts via text or email and also connects to the smart home devices. It’s paid for itself through avoiding damage by early awareness of leak alerts alone.
