You shouldn't come home to a wall of heat.
The aircon was sitting idle all day. You're paying to cool the home for the next two hours. There's a better way: your home should be ready for you.
Climate.
Comfort tuned for Singapore.
Aircon that responds to humidity, not just temperature. Bathroom fans with presence + humidity logic. Mould prevention for the times you're away. Designed for the climate you actually live in.
Most smart climate systems are American.
The dominant smart home platforms (, Google Home, Alexa) were designed in markets where climate means heating in winter and cooling in summer. The unit of comfort is temperature: a thermostat, a setpoint, a schedule. This works fine in Texas or Tokyo or Toronto.
It doesn't work in Singapore. Here, the unit of comfort is humidity, not temperature. A bedroom at 27°C and 60% humidity feels comfortable for sleeping. A bedroom at 25°C and 80% humidity feels clammy and overheated. American smart home templates can't express this; they think in degrees.
Haiteku-designed climate systems think in humidity. Aircon doesn't run all night; it cycles based on what the bedroom actually needs. Bathroom fans don't just run on a timer; they extend based on shower humidity. Living areas are protected from mould during the day when the household is away. SP bills come down, sleep gets better, and the home doesn't quietly mould while you're at work.

What it could look like for your home.
- Example 1 · Master bedroom aircon at night
Aircon runs at sleep setpoint (~25°C) when household is in the room. If humidity drops below 60%, aircon switches off and ceiling fan drops to speed 1. If humidity rises above 65%, aircon resumes at low fan speed. By morning, fan steps up first, aircon Dry mode if needed. Typical SP bill reduction: 15–25% on bedroom aircon usage, with no reduction in sleep comfort.
- Example 2 · Living room mould prevention while household is at work
Humidity sensor in the living area. When household is away and humidity exceeds 75% for 2+ hours, aircon switches to Dry mode at moderate setpoint (28°C, low fan). Runs until humidity drops to 65%, then shuts off. Energy-conscious; Dry mode uses less power than Cool mode. Prevents the slow mould build-up that's the #1 long-term Singapore home complaint.
- Example 3 · Bathroom presence + humidity exhaust
Presence sensor inside the bathroom + humidity sensor. Fan runs for 5 minutes after presence ends (toilet/handwash). If humidity is above 75% (post-shower), fan extends until humidity drops to baseline + 5%. Wall switch override for manual control. Solves both odour (toilet) and mould (shower) without the homeowner thinking about either.

Essentials or Professional: pick the depth that fits.
Climate can be implemented at two depths.
for households who want smarter aircon control without rewiring everything.
- Smart adapter (Sensibo or Ambi Climate) on 2–3 priority aircons (master bedroom + 1–2 others), OR native smart control if you have Daikin/Mitsubishi
- 2–3 temperature/humidity sensors in main living areas
- Basic mould-prevention automations (humidity-triggered Dry mode)
for households who want full climate orchestration and the smartest energy efficiency.
- Smart control on every aircon in the home
- Ceiling fan smart switches paired with aircon (fans step in when aircon idles)
- Room-by-room temperature, humidity, and presence sensors
- Window/door sensors that pause aircon when opened
- Bathroom presence + humidity exhaust automations
The Consult conversation surfaces which depth fits your household. Most HDB clients land at Essentials; landed homes and households with specific climate concerns (mould-sensitive, energy-conscious, helper comfort) tend toward Professional.

What we typically use.
Aircon control
Sensibo Air, Ambi Climate, or smart-aircon-native units (Daikin Smart Control, Mitsubishi MELCloud).
Humidity/temp sensors
Aqara T1 or FP300 (combined presence + temp + humidity).
Presence sensors
Aqara FP1 (basic) or FP2 (precision, with zones).
Bathroom fan switches
Aqara H2 (smart switch, with manual override).
Ceiling fan control
Broadlink RM5 (universal IR/RF) or smart ceiling fan if specified.
For aircon specifically: most existing Singapore aircons can be made smart with a Sensibo or Ambi controller (~S$150–200 per unit). New installations of smart-native aircons (Daikin, Mitsubishi) are also fully supported.
Apple Home vs Home Assistant for climate.
Climate is one of the areas where is meaningfully more capable than Apple Home. Apple Home's automation logic struggles with compound conditions like "humidity above X for Y minutes AND household away." Home Assistant handles these natively.
For Apple Home builds, we design climate recipes around the platform's constraints: simpler thresholds, single-condition triggers, more reliance on time-of-day rules. The household still gets meaningful improvements, just expressed in a less sophisticated way. For Home Assistant builds, we design climate recipes that take full advantage of compound logic. The "master bedroom night humidity balance" recipe is meaningfully better on HA, and for households who care most about climate intelligence, this is sometimes the deciding factor in choosing the open path.
