The thermometer pairs seamlessly with SunAura Thermal heating systems. When combined with a WiFi thermostat, you can check both the ambient room temperature and the heating set-point from the SunAura app, and adjust your schedule remotely for complete home climate control.
Frequently Asked Questions
What does the dual display show?
The display shows the current room temperature and the target temperature side by side, so you can instantly see whether the room has reached the level you set on your thermostat.
Can I use it with a non-SunAura heating system?
Yes — it works as a standalone room climate monitor with any heating system, or simply on its own. For full remote control we recommend pairing it with a SunAura WiFi thermostat.
How do I choose between the 16A and 25A variants?
The load rating should match your heating zone’s total connected load. 16 A covers most single-room electric heating loads; choose 25 A for larger zones, multiple mats or higher-density systems. Our engineers can confirm the right rating from your project details.
Is the device certified?
Yes. The thermometer and hygrometer are CE and RoHS certified and manufactured under ISO 9001 and ISO 14001 quality and environmental standards.
If you are looking for an indoor thermometer hygrometer for home comfort monitoring, the SunAura KC01 gives you a clean dual-display readout of current and target room temperature with white backlight and child lock — equally useful as a digital room temperature humidity meter for nursery, bedroom, study or greenhouse, and as a wall-mounted hygrometer for wine cellar and warehouse climate checks. Unlike a thermostat, this unit does not switch any heating load; its job is to show you the room climate accurately so you can adjust your heating, humidifier or ventilator with confidence. The notes below explain where to place it, why humidity matters as much as temperature, how to calibrate it, and how to order it from SunAura as a single unit, a trade stock item or an OEM private-labelled product.

Where to Use Your Thermometer-Hygrometer
The KC01 is a monitoring instrument, not a heating controller, so it earns its place wherever a stable, readable room climate matters more than switching a load:
- Nurseries and babies’ rooms — keep the room around 20–22 °C and the relative humidity in the comfortable 40–60 % range; the soft white backlight lets parents check the reading at night without fully waking the baby.
- Bedrooms and studies — track overnight temperature and humidity so bedding feels neither clammy nor dry, and so you can tune a radiator or underfloor heating schedule to the actual room rather than a guess.
- Wine cellars and spirit cabinets — long-term storage wants steady, cool, stable conditions and controlled humidity; a wall-mounted hygrometer warns you before corks dry out, labels peel or sediment shifts.
- Warehouses, storerooms and archives — monitor paper, fabric, wood or electronic stock against moisture damage and condensation, especially in unheated corners where a heating thermostat would never be installed.
- Greenhouses, grow rooms and plant corners — humidity swings around seedlings, cuttings and tropical plants are easier to manage when you see the trend on one display next to the watering schedule.
- Music rooms and collectables — wooden instruments, vinyl records, books, framed prints and old cameras all last longer when temperature and humidity stay inside a narrow band year-round.
- Offices, clinics and classrooms — a public wall-mounted monitor gives staff, students and visitors a quick, trustworthy room climate reference without anyone having to open a phone.
For best accuracy, mount the unit on an interior wall at roughly eye level, away from direct sunlight, radiators, underfloor heating outlets, draughts, windows, extractor fans and kitchen steam. Do not cover the vents on the housing, and avoid tucking it behind a curtain or inside a closed cabinet, because the sensor needs to sample the actual room air. The display can be calibrated against a trusted reference thermometer if you need the KC01 to match a nursery, wine cellar or quality-control specification.
Why Humidity Matters as Much as Temperature
A room that feels fine at 21 °C can still be uncomfortable if the relative humidity is wrong. Below about 30 % RH, skin, throat and eyes feel dry, wooden furniture and floors start to shrink and crack, and static electricity becomes noticeable on carpets and door handles. Above about 60 % RH, walls and windows can develop condensation, mould spores find a foothold in corners, and bedding and upholstery feel clammy even when the thermometer looks normal. The comfortable band for most homes sits between 40 % and 60 % RH, which is why a combined thermometer-hygrometer is more useful than a thermometer alone: it tells you not just how warm the air is, but whether the air is actually healthy to breathe. Use the KC01 to compare readings in different rooms, spot damp corners after rain, and decide when to switch on a humidifier, ventilate the room or adjust your heating schedule. Over a winter week, that single glance at the wall can save more discomfort than any expensive upgrade.
Calibration, Placement and Care
Treat the KC01 like any other precision instrument. Mount it on an interior wall at breathing height, roughly 1.2–1.5 m above the floor, and keep it at least half a metre away from radiators, external doors, extractor fans and kitchen kettles — all of these create local hot or dry spots that distort the reading. If you need the KC01 to match a calibrated reference thermometer for a nursery, wine cellar or quality-control room, place the two instruments side by side for an hour, compare the readings and adjust the offset in the settings menu until they agree. Wipe the face with a dry soft cloth; do not spray liquid directly onto the screen. The low-power design gives long standby life, so the monitor can stay on the wall year-round without attention. When you move house or refurbish a room, take the KC01 with you — it screws or stands on a desk, and it resumes its reading within minutes of being placed.
Packing, Warranty and After-Sales
Every KC01 ships in a colour box with the thermometer-hygrometer itself, fixing screws and the multi-language user guide. The unit carries a 2-year warranty with direct after-sales support from SunAura — spare parts, offset calibration help and placement guidance by WhatsApp in English, German, French and Chinese. Distributor and OEM customers can request extended terms, private-labelling on the housing and retail box, custom gift packaging and project-specific certification documents for tenders. Whether you buy one for the nursery shelf or a carton for your catalogue, the same factory team answers your questions before and after the sale.
More Questions
1. Does this unit switch a heater, humidifier or dehumidifier on and off?
No. The KC01 is a display and monitoring instrument: it shows current and target room temperature with white backlight and child lock, but it has no relay outputs and does not switch any heating, humidifying or ventilating load. Use it to read the room climate, and adjust your separate heating or humidifier manually or through a paired WiFi thermostat.
2. Can I use it as a standalone room monitor without SunAura heating?
Yes. The thermometer-hygrometer works on its own in any indoor room, regardless of the heating brand. It runs on low power for long standby life, sits on a desk or fixes to a wall, and shows the room temperature and target temperature side by side.
3. Where should I mount it in a baby room?
Fix it on an interior wall at eye level, away from the cot, direct sunlight, radiators and windows. Aim for a stable 20–22 °C and around 40–60 % relative humidity; the soft white backlight is gentle enough for night checks without fully waking the baby.
4. Is it suitable for a wine cellar or unheated storeroom?
Yes — as a wall-mounted monitoring instrument it is commonly used in wine cellars, archives and warehouses to track long-term temperature and humidity trends. It does not heat or ventilate the space; it simply gives you an early warning when conditions drift outside the band your stock needs.
5. Can I buy it wholesale or with my own branding?
Yes. SunAura supplies the KC01 to distributors and OEM partners worldwide with wholesale price breaks, EXW or FOB quotations, CE and RoHS certification documents and private-labelling on the housing and retail box. MOQ and lead time depend on quantity — send your enquiry for a same-day offer.
6. How does it pair with a SunAura WiFi thermostat?
The KC01 itself is a local display instrument. To check room temperature remotely from your phone, pair the room with a SunAura WiFi thermostat such as the K1M or K2M, which reports the measured room temperature in the Tuya-compatible app; the KC01 then acts as a trusted on-wall reference for calibration and spot checks.
FAQ (continued)
7. What accuracy and humidity range can I expect from an indoor thermometer hygrometer for wine cellar monitoring?
The KC01 is built for everyday indoor comfort monitoring, with a stable NTC-style temperature reading and a relative-humidity sensor aimed at the 20–80 % RH band typical of homes, cellars and storerooms. For wine storage we recommend mounting it away from the cellar door and direct bottle chills, then comparing it for a week against a trusted reference hygrometer before relying on the trend; it is a monitoring aid, not a calibrated laboratory instrument.
8. What about thermometer hygrometer battery life, wall mounting and desk stand options?
The unit uses a low-power design for long standby life and runs continuously from its internal supply; the white backlight wakes only when you check the reading, so it does not drain the battery over time. It fixes to the wall with the included screws on any interior surface, or simply stands on a desk, shelf or nursery cabinet — no wiring, no network setup and no app account required for basic temperature and humidity display.
Whether you are outfitting a single nursery shelf, a home wine corner, a warehouse stock room or a distributor catalogue, the SunAura KC01 indoor thermometer and hygrometer is a low-cost, high-readability way to keep an honest eye on room climate all year round.
