The Sonoff RL560 is a 5-meter sensor extension cable designed to give you more flexibility when positioning your monitoring devices. Using an RJ9 4P4C connector, it allows you to move sensors further away from the main unit without compromising signal stability, which is particularly useful if your controller is mounted in a location that isn't ideal for accurate readings. This black cable is compatible with both the TH Elite and TH Origin series, supporting various probes such as the THS01 temperature and humidity sensor, the waterproof DS18B20 and WTS01 models, and the MS01 soil moisture sensor. Depending on the probe used, it can be part of a chain extending up to 60 meters for temperature and humidity sensors or up to 10 meters for soil moisture probes. Its technical build ensures reliability with an insulation resistance of at least 5 MΩ and a conductor resistance not exceeding 10 Ω, while the hot-pluggable design means you can connect or swap sensors without needing to power down your system.
