SensorPush offers several sensor models and accessories to meet different monitoring needs. Whether you're monitoring a wine cellar, humidor, greenhouse, freezer, or vacation home, this guide will help you choose the right combination of products.
The Sensor Models
All three sensor models are the same size, measure temperature from -40°F to 140°F (-40°C to 60°C) and relative humidity from 0 to 100%, and also show dewpoint and VPD in the app.
The HT1 is our entry-level sensor. It measures temperature and humidity with good accuracy. It's reliable and works well indoors and in places that stay protected from water, like humidors, refrigerators, closets and living spaces.
The HT.w is our water-resistant model. It includes everything the HT1 offers plus an updated design with o-ring seals and a protective membrane over the humidity sensor that shields it from splashes. It's also a bit more accurate than the HT1. The battery compartment has a simple screw-on cap for easy replacement. The HT.w is made in the USA. This is our most popular sensor and the best all-around value for most customers.
The HTP.xw is our premium sensor. It includes all the HT.w features plus a barometric pressure sensor and even more accurate temperature and humidity readings. If you need pressure monitoring for weather tracking or altitude-related applications, or want the most accurate readings possible, this is the one to choose.

What You Need to Get Started
You set up SensorPush sensors with the free SensorPush app on an iPhone, iPad or Android phone or tablet. The current app needs iOS 15 or later, or Android 8.0 or later. There is no Windows or Mac app, but once you have a Gateway you can also view your sensors in a web browser.
Do I Need a Gateway?
The SensorPush G2 WiFi Gateway is the key to remote monitoring. The G2 replaces our original G1 WiFi Gateway, which has been discontinued. If you already have a G1, it keeps working, and you can add a G2 to the same account at any time.
Without a Gateway, your sensors communicate directly with your phone via Bluetooth, which limits you to monitoring only when you're physically nearby.
You need a Gateway if you want to: monitor when away from home, receive alerts while at work, access the web dashboard, receive email alerts, or share access with family members who aren't physically present.
Without a Gateway, you can still use the sensors effectively - they continuously log data while you're away, and when you return within Bluetooth range, the app will sync the stored readings to your phone. Each sensor stores a limited history on board (about 20 days for the HT1, 45 days for the HT.w and 30 days for the HTP.xw), so be sure to come back within range before then, or the oldest readings will be replaced. Many customers start this way and add a Gateway later when they realize how valuable remote access would be.
Gateway Placement Requirements
The Gateway needs three things simultaneously: Bluetooth range to your sensors (up to about 325 feet line-of-sight, much less through walls), a 2.4 GHz WiFi network, and power (the G2 runs from its included USB-C charger and must stay plugged in).
How Many Sensors Do I Need?
Each sensor measures conditions at its specific location. If you want to know the temperature in multiple locations, you'll need a sensor in each location. A single phone or Gateway can handle many sensors at once.
Common Setup Examples
For a home monitoring setup (basement, attic, crawl space): Start with 2-3 HT.w sensors and one G2 Gateway. Place the Gateway in a central location, then distribute sensors to the areas you want to monitor.
For a wine cellar: One HT.w or HTP.xw sensor is usually sufficient for a typical home wine cellar. Add a Gateway if you want remote access and alerts.
For a cigar humidor: One HT1 sensor inside the humidor works well. If you want the best possible accuracy, choose the HTP.xw, our most accurate sensor.
For a refrigerator or freezer: Any model works. See Can I use SensorPush in a refrigerator, freezer, or walk-in cooler? for tips on signal range and batteries in the cold.
For vacation property or RV: HT.w or HTP.xw sensors for their water resistance, plus a Gateway for remote monitoring.
Multiple Gateways
You can have multiple Gateways on the same account. They can be in the same location to expand coverage or in completely different locations, and you can mix G1 and G2 Gateways.
