MOCREO Thermometer Hygrometer ST9 IP67 Probe — 4.9 ft Cable, Hub Required

The MOCREO ST9 is a compact temperature and humidity sensor with an IP67-sealed remote probe that reports readings to a MOCREO hub for reliable monitoring in damp or enclosed spaces.

Designed as an add-on sensor for an existing MOCREO system, the ST9 sends precise temperature and relative humidity readings back to your hub over Bluetooth so you can monitor environments an ordinary meter cannot reach. Its 4.9-foot cable lets you place the waterproof probe where moisture or limited space would otherwise ruin a sensor body—ideal for humidors, reptile terrariums, greenhouses, gun safes, and crawlspaces.

How does the ST9 keep readings accurate in wet or confined spots?

The sensing element is housed inside an IP67-rated probe that keeps water and vapor away from the electronics, extending lifespan and measurement stability. The sensor reads a wide temperature range and high humidity levels with tight tolerances suitable for hobbyist and light professional use.

• IP67 sealed probe repels moisture and splashes.
• Probe cable length 4.9 ft for flexible placement inside enclosures.
• Temperature range −40°F to 221°F; ±≈0.5°F typical accuracy.
• Humidity 0–100% RH; typical accuracy around ±3% RH.

What does “hub required” mean and which hubs work?

ST9 is not a standalone display device; it communicates with a MOCREO hub which relays data to the phone app and handles alerts. It’s compatible with current and some legacy MOCREO hubs so it integrates into an existing monitoring network.

• Works with MOCREO hubs: H3, H5-Lite, H5-Pro, H6-Lite, H6-Pro, and older H1/H2 models.
• Hub connects to the app and sends push, email, and audible alerts.
• Bluetooth range about 131 ft open line of sight; typical home coverage.
• One hub supports up to 30 sensors; no subscription fees.

How will I be notified if conditions go out of range?

When paired with a MOCREO hub, ST9 uses the app and the hub’s built-in alarm to alert you if temperature or humidity crosses preset thresholds. You receive timely warnings via three channels so you can act before items or animals are harmed.

• App push notifications for immediate mobile alerts.
• Email notifications for logged incidents or sharing with others.
• Audible alarm from the hub to warn nearby occupants.
• Readable history and exportable graphs for trend analysis up to two years.

Who this sensor is for: The MOCREO ST9 suits hobbyists and caretakers who need a rugged probe inside damp or cramped spaces—cigar collectors, reptile keepers, greenhouse growers, gun safe owners, and property managers who already use or plan to use a MOCREO hub. If you need a self-contained meter with a screen or a simple fridge probe, consider other MOCREO models; if you want long-lasting battery life, waterproof sensing, and integration into a multi-sensor home or shop system, the ST9 is built for that role.
