La Crosse Technology C85845-INT Review: Colour Display, No Wi-Fi, No Fuss
The C85845-INT colour LCD display shows indoor and outdoor temperature, humidity, forecast icons, and atomic time — all without Wi-Fi or app connectivity.
The C85845-INT suits anyone who wants a clear, colour display for indoor and outdoor conditions without the setup complexity of a Wi-Fi station. It is the right choice if you do not need app access, remote monitoring, or wind data — and simply want accurate temperature, humidity, and forecast information on a well-lit display in your home.
The C85845-INT is part of La Crosse Technology’s colour display lineup — a step up from a basic thermometer in terms of information, but deliberately kept offline. No La Crosse View app, no cloud, no Weather Underground. For many buyers that is exactly the point. For full context on where it sits in the La Crosse range see the La Crosse weather station overview.

- Animated barometric forecast icons react to pressure trends
- Atomic time with auto DST and 7 time zone settings
- Customisable hi/lo alerts for temperature and humidity
- No app or network setup required — after installing batteries and pairing the outdoor sensor, the station is ready within a few minutes

- No data history beyond current hi/lo records — no graphing
Display, Setup, and Day-to-Day Use
Display
The C85845-INT’s colour LCD measures 8.98 by 5.43 inches — large enough to read from across a room. The forecast icons with trend arrows are a distinguishing feature — rather than a static weather symbol, the icons respond to barometric pressure trends, giving a more dynamic indication of whether conditions are likely to improve or deteriorate. The colour comfort bars show indoor and outdoor humidity levels on a scale from dry to humid, with colour coding that makes the reading immediate without needing to interpret a number.
Brightness is adjustable between high, low, and off — but only when running on the AC adapter. On battery-only power the backlight activates temporarily on demand rather than staying on. The AC adapter is included, so this is not a cost issue — just worth knowing if you plan to place the station somewhere without an outlet nearby.
Setup
Setup is straightforward. Plug in the AC adapter, install batteries in the outdoor TX141TH-B sensor, and allow the display to pick up the signal — typically within a few minutes. Mount the outdoor sensor on a north-facing wall or shaded location, vertically, at least 6 inches below eaves to avoid direct sunlight skewing temperature readings. La Crosse recommends allowing 7 to 10 days after setup for the barometric pressure readings to calibrate to your local elevation before relying on the forecast icons.
Day-to-day use
After reviewing long-term owner reports across major retailers and weather enthusiast communities, the strengths most frequently mentioned are the display clarity, the reliability of the wireless connection once set up, and the value of having heat index and dew point alongside the basic temperature reading. The most common criticism is the absence of any data history — the station shows current readings and today’s hi/lo, but there is no way to review yesterday’s data or graph trends over time. For owners who primarily use the station as a home comfort reference rather than a data logging tool, this limitation rarely comes up.
Who Should Buy the C85845-INT
- You want indoor and outdoor temperature and humidity on a clear colour display without any app or network setup
- Heat index, dew point, and comfort level indicators matter to you — especially useful in humid climates
- You want an atomic clock with a well-lit display as a bedroom or kitchen station
- Simplicity is the priority — no configuration beyond sensor placement
- You are buying as a gift for someone who does not want to deal with app connectivity
- You want to check your weather from your phone — the C85845-INT has no app or remote access
- Wind speed or rainfall measurement is part of your requirements
- You want to contribute to Weather Underground or CWOP
- Data history or trend graphing matters to you
- You need the station to work without being near an outlet — battery-only operation limits backlight functionality
If the limitations above matter to you, the La Crosse 328-69357 adds Wi-Fi, app connectivity, and cloud data history at a higher price point. The La Crosse 328-69357 vs Ambient WS-2902C comparison covers the step-up options if you also want wind data.

Alternatives Worth Considering
The C85845-INT is the right station for a specific type of buyer. If your needs fall outside its scope, these are the natural alternatives within the same price range:
- Best if you want Wi-Fi and app access: La Crosse 328-69357 — adds Wi-Fi, La Crosse View app, and up to 2 years of cloud data history at a higher price point.
- Best if you want wind and Weather Underground upload: Ambient WS-2902C — adds anemometer, UV index, and public network upload, at a similar or slightly higher price.
- Best if you want a colour display without Wi-Fi at a similar price: La Crosse S77925 — comparable colour display station, also no Wi-Fi, different form factor.
- Best if you only need basic indoor temperature: A simple standalone indoor thermometer — no outdoor sensor or forecast needed, lower cost.
Frequently Asked Questions
Does the La Crosse C85845-INT have Wi-Fi?
No. The C85845-INT does not have Wi-Fi, does not connect to an app, and does not upload to any cloud platform. All data is displayed locally on the colour LCD console. If app connectivity or remote monitoring matters, the La Crosse 328-69357 is the Wi-Fi-enabled alternative in the La Crosse lineup.
What does the La Crosse C85845-INT measure?
The C85845-INT measures indoor and outdoor temperature and humidity, barometric pressure with animated forecast icons, heat index, dew point, and daily hi/lo records with customisable alerts. It also displays atomic self-setting time and date with automatic DST adjustment. It does not measure wind, rainfall, UV, or solar radiation.
How far does the C85845-INT outdoor sensor transmit?
The TX141TH-B wireless sensor transmits up to 330 feet (100 metres) in open air. Walls, floors, and metal surfaces reduce effective range. La Crosse recommends mounting the sensor vertically on a north-facing or shaded wall, at least 6 inches below eaves to avoid direct sunlight affecting temperature accuracy.
What power does the La Crosse C85845-INT use?
The display console runs on the included 5V AC adapter as primary power — required for constant backlight and adjustable brightness. Three AA batteries (not included) provide backup during power outages. On battery-only power, the backlight operates on demand rather than staying on to preserve battery life. The outdoor sensor runs on 2 AA batteries (not included).
