About This

• Read This First - This Sensor Needs a MOCREO Hub - ST9 is an add-on for a system you already own, not a standalone meter: it talks to a MOCREO hub over Bluetooth, and the hub is what puts readings on your phone. It works with MOCREO hubs H3, H5-Lite, H5-Pro, H6-Lite and H6-Pro, and with the older H1 and H2, all managed in one app alongside the sensors you already have. Keep it within about 131 ft of the hub in open line of sight, which covers a normal house or a shop floor. If you do not own a hub yet, buy one with it.
• Get a Reading From the Spots Ordinary Meters Get Wrong - A reptile tank, a cigar humidor, a greenhouse, a gun safe or a crawlspace is exactly where a plain hygrometer drifts, fogs up or simply does not fit. This thermometer hygrometer keeps the body outside and sends only the probe in on a 4.9 ft cable, so you finally get a trustworthy number from inside the enclosure instead of guessing from a meter sitting on a shelf.
• Accurate Where It Is Wettest, Season After Season - Water vapor is what kills most hygrometers, so the probe here is sealed to IP67 and keeps the sensing chip away from moisture; it reads from -40F to 221F and 0 to 100% RH to within about 0.5F and 3% RH, which is close enough that one keeper compared it against three other brands and found the humidity within roughly one percent.
• Know Something Is Wrong Before Your Animals or Cigars Do - Paired with a MOCREO hub, this temperature humidity sensor watches your set high and low limits and reaches you three ways when a reading goes out of range: an app push, an email, and an audible alert from the hub itself, so a heat lamp that failed overnight or a humidor drying out does not go unnoticed until morning.
• See the Trend, Not Just This Minute - Readings build into temperature and humidity graphs in the app and can be exported for up to two years, which turns a hunch about a slowly drying humidor or a swinging greenhouse into something you can actually look at. One hub carries up to 30 sensors, so you can start with this one and add rooms as you go, with no monthly fee.
• Charge It and Leave It Alone - The built-in rechargeable battery runs for around two years on a charge, so a sensor tucked into a safe or a crawlspace does not need a battery run every season. A note on what it is not: ST9 has no screen of its own and reads through the app, and it is a temperature and humidity sensor, so if all you need is a fridge or freezer probe, look at MOCREO MS2 or ST8 instead.
