3,000+ Integrations. Why Stop at Home?

The simplest win is schedule-based control: your office cools down before staff arrive, maintains comfort during business hours, and ramps back when the last person leaves. Home Assistant can automate this based on calendar events, occupancy sensors, or time-of-day schedules — or a combination of all three. If you're working late, a button press or phone tap can extend the cooling window.

Zone control is another big one for multi-room offices. There's no reason to heat the meeting room to 22°C all day when it's only used for two hours. With temperature sensors and smart thermostats or zone controllers, Home Assistant can manage each space independently — rooms warm up before meetings and return to setback mode afterwards.

Home Assistant integrates with most commercial and prosumer HVAC systems, including Mitsubishi, Daikin, Fujitsu, Trane, and Nest. If your unit has a control interface — wired or IR — there's a very good chance there's an integration already built. And unlike proprietary apps, everything is visible in one place.

A morning open routine might: unlock the front door, turn on the lights in reception, set the HVAC to comfort mode, power on the POS system and displays, start the coffee machine, and send a notification to the manager confirming everything is ready. A closing routine does the reverse — and can be triggered by a single button, a voice command, or automatically when the last presence sensor goes quiet.

Home Assistant integrates with AV equipment, digital signage, PA systems, and commercial displays through brands like Sony, Samsung, LG, and via HDMI-CEC control. Want the screens in the waiting area to display the day's schedule when the office opens and switch to screensaver mode after hours? Home Assistant and other DIY smart home tools make this possible.

Because Home Assistant has over 3,000 official integrations, the chances are very good that whatever equipment you already have can be connected. Point-of-sale peripherals, network switches, printers, label makers, refrigeration units, coffee machines — the community has built integrations for an enormous range of commercial equipment that proprietary business automation systems simply don't support.

Smart locks with auto-generated access codes are the starting point. Home Assistant can create unique PIN codes for each booking, synced from your calendar or channel manager, that activate at check-in and expire at checkout. No key handovers, no lockbox combinations — guests get a seamless entry, and you get a full audit trail of arrivals and departures across every property.

Climate control between guests is where the savings stack up. Home Assistant can drop heating and cooling to setback mode after checkout, then bring the property back to a comfortable temperature before the next guest arrives. Multiply that across several properties and multiple turnovers a week, and the energy savings are significant. Occupancy sensors can also confirm vacancy so cleaners know exactly when to head over.

For boutique hotels and multi-room properties, Home Assistant can manage room-level automations at scale. Each room gets its own climate schedule, lighting scenes, and access code — all managed from a central dashboard. Welcome lighting on first entry, automatic scene resets after checkout, and real-time occupancy visibility across the entire property. It's the kind of automation that usually requires an expensive commercial BMS — delivered at a fraction of the cost.
