Basalte Keypads: Fibonacci & Sentido Explained

Walk up to a wall in a home fitted with a standard keypad and you see a keypad — a plastic or metal plate with labelled buttons, doing its job and looking like what it is. Walk up to a Basalte keypad and, until you're close enough for its hidden sensor to notice you, you see a clean panel of brushed brass or glass, indistinguishable from the wall finish around it. Then it wakes up. That difference — a control point that behaves like a considered piece of the architecture rather than an accessory bolted onto it — is the entire reason a Belgian keypad manufacturer has a place in a guide that otherwise covers Crestron, Lutron and KNX.

This guide covers Basalte's two keypad lines, Fibonacci and Sentido — what they actually are, their real specifications and finishes, and an honest comparison with the standard keypads most automation systems ship with. Written for architects, interior designers, and homeowners in Ahmedabad and Rajkot for whom the physical interface matters as much as what it controls.

What Basalte Actually Is

Basalte is a Belgian manufacturer of premium keypads and room controllers built specifically to sit inside high-end automation systems rather than as a standalone smart-home brand — its keypads don't run their own automation logic, they act as the physical interface into whichever platform (Crestron, Lutron, or KNX) is actually running the home. That distinction matters: Basalte is a hardware and industrial-design specialist, and it partners with rather than competes against the platforms this site covers elsewhere.

Both keypad lines share a unibody design philosophy — the touch-sensitive surface and the cover are combined into a single article rather than a plate over a separate switch mechanism, which is part of why the finish reads as continuous rather than assembled.

Sentido was Basalte's original touch switch, and Fibonacci arrived later as the flagship redesign, shown at CEDIA — the custom-install industry's own trade show — as native Crestron and Lutron integration alongside its existing KNX support. That progression matters for how the two lines are positioned today: Sentido isn't an older or lesser product being phased out, it's the multifunction line that added a temperature sensor and a broader finish palette, while Fibonacci pushed the flagship design and proximity-sensing further at a narrower, all-metal finish range.

Both lines are wired devices, installed the same way a standard in-wall keypad would be — behind a standard back box, on the automation platform's own bus (Cresnet, Lutron's wiring, or KNX twisted pair) rather than wirelessly. That means the decision to specify Basalte has to be made at the electrical design stage, same as any other keypad, not retrofitted casually after walls are closed.

Fibonacci: The Flagship Keypad

Fibonacci is Basalte's flagship keypad — a compact unibody touch panel measuring roughly 3.15" x 4.72" x 0.35" (80 x 120 x 9mm), small enough to sit unobtrusively beside a door frame. Its separate touch-sensitive surfaces each control a distinct function via short and long press, and touching more than one surface simultaneously triggers additional comfort functions — room toggle, a scene sequencer, and an RGB sequencer among them. A hidden proximity sensor detects approach and gently illuminates the backlit, customizable labels, which can show text or icons rather than fixed engravings. The buttons themselves are precision-engineered from premium metals, and Fibonacci is available only in luxury finishes — brass, bronze, and nickel.

Sentido: The Multifunction Touch Switch

Sentido is Basalte's multifunction touch switch, using the same multitouch philosophy across a four-button layout, with additional multi-touch points on the side bezels for further control. Every Sentido keypad carries an integrated temperature sensor and thermostat logic, reporting ambient temperature onto the automation bus it's connected to — so a single keypad handles both lighting/scene control and room temperature reporting rather than needing a separate thermostat. Sentido ships in a wider finish range than Fibonacci — aluminum, bronze, glass, and leather — giving it more flexibility to match varied interior palettes.

Platform Compatibility — Crestron, Lutron, KNX

Both Fibonacci and Sentido are available for Crestron, Lutron, and KNX systems, which is what makes Basalte a genuinely platform-agnostic choice rather than something that locks a project into one ecosystem. On Crestron specifically, Sentido for Cresnet is manufactured and validated under Crestron's own Integrated Partner Program — third-party validation rather than an unverified compatibility claim — and integrates with Crestron via serial communication alongside native Cresnet versions. On Lutron, Sentido integrates with HomeWorks QS. On KNX, both keypads work as native KNX bus devices, controlling lights, temperature, and motorized shades directly over the KNX standard.

Deseo: The Companion Room Controller

Basalte's product family also includes Deseo, a dedicated HVAC control panel with its own integrated temperature sensor, thermostat logic, and a multicolour OLED display — Crestron Connected and KNX compatible. Deseo isn't a keypad in the Fibonacci/Sentido sense; it's the answer for a room that needs a more capable climate interface than Sentido's built-in sensor provides, without giving up the same design language across the property. Worth knowing it exists as part of a coherent Basalte specification, even though this guide's focus stays on the two keypad lines.

Basalte vs. a Standard Keypad: An Honest Comparison

A standard Crestron or Lutron keypad does the same core job — triggering scenes, controlling lighting and shading — at a materially lower cost, with a wider range of standard finishes and a shorter lead time, since it isn't a specialist import. For a project where the interface itself isn't a design priority, or budget is genuinely tight, a standard keypad is very often the right call, and a good integrator should say so rather than upsell a design object nobody asked for.

Basalte earns its place where the client has explicitly prioritized the tactile and visual quality of every touchpoint in the home — a design-led villa, a flagship room, an entry sequence a client wants to feel considered the moment they walk in. It's a genuinely different value proposition from a standard keypad, not simply a more expensive version of the same thing, and framing it as an upgrade rather than a design decision is how a client ends up disappointed either way.

Worth setting expectations on maintenance too, since it's rarely raised until after handover: a brushed brass Fibonacci finish will develop a patina over years of touch, the same way a brass door handle does, and a glass Sentido surface shows fingerprints more visibly than a matte metal one. Neither is a defect — it's the material behaving as that material does — but a client choosing a living finish like brass should know that going in, rather than being surprised the first time it doesn't look brand new.

Specifying Basalte for an Ahmedabad Home

A representative Basalte specification on a premium Ahmedabad or Rajkot villa typically covers Fibonacci at the primary entry points and formal living spaces — where the finish quality is most visible and most frequently touched — with Sentido specified in bedrooms and family spaces where its integrated temperature sensor removes a separate thermostat from the wall. Pricing for Basalte hardware is genuinely project- and finish-specific — brass, bronze, and glass carry different costs, and it's quoted as part of the overall system design rather than a fixed per-unit figure, unlike the more standardized platform pricing in our cost breakdown guide.

Why Agrima Specifies Basalte

Agrima Solutions is a home automation company with offices in Ahmedabad and Rajkot — KNX Gold Partner, Official Crestron Partner in Gujarat, and a Lutron dealer — and Basalte is one of our listed brand partners specifically for projects where the physical interface is part of the design brief, not an afterthought. We specify it where a client has genuinely prioritized that, and recommend a standard keypad honestly where they haven't — the platform underneath (Crestron, Lutron, or KNX) does the actual automation work either way, so the choice between Basalte and a standard keypad is a design decision layered on top of a system design decision, not a substitute for one.

Frequently Asked Questions

What is Basalte?

A Belgian manufacturer of premium keypads and room controllers designed to be the physical interface into a Crestron, Lutron, or KNX automation system — not a standalone automation platform itself.

What's the difference between Fibonacci and Sentido?

Fibonacci is Basalte's flagship keypad, available only in metal finishes (brass, bronze, nickel), with proximity-triggered backlighting. Sentido is a multifunction touch switch with an integrated temperature sensor and thermostat logic, available in a wider finish range including glass and leather.

Does Sentido need a separate thermostat?

No — Sentido has an integrated temperature sensor and thermostat logic built in, reporting ambient temperature onto the automation bus directly, which removes the need for a separate wall-mounted thermostat in that room.

Is Basalte compatible with Crestron?

Yes. Sentido for Cresnet is manufactured and validated under Crestron's own Integrated Partner Program, and both Fibonacci and Sentido are available in Crestron-compatible versions.

Is Basalte compatible with Lutron?

Yes — Sentido integrates with Lutron HomeWorks QS, and Fibonacci is also available for Lutron systems.

Is Basalte compatible with KNX?

Yes, natively — both keypads work as KNX bus devices and can control KNX-compatible lights, temperature, and motorized shades directly.

What finishes does Fibonacci come in?

Brass, bronze, and nickel — Fibonacci is available only in premium metal finishes, precision-engineered rather than standard plastics.

What finishes does Sentido come in?

Aluminum, bronze, glass, and leather — a wider range than Fibonacci, giving more flexibility to match varied interior finishes.

What is Basalte Deseo?

A dedicated HVAC control panel in the Basalte family, with its own integrated temperature sensor, thermostat logic, and a multicolour OLED display, compatible with Crestron Connected and KNX — a more capable climate interface than Sentido's built-in sensor, for rooms that need it.

How does the multitouch function work on Fibonacci?

Touching more than one of Fibonacci's touch-sensitive surfaces at the same time activates additional comfort functions — including room toggle, a scene sequencer, and an RGB sequencer — beyond the individual short/long-press functions of each surface alone.

Is Basalte worth it over a standard Crestron or Lutron keypad?

It depends on the priority. A standard keypad does the same core scene and lighting control at a materially lower cost with shorter lead times. Basalte earns its place specifically where the physical interface's design and finish quality is a genuine priority for the client — it's a design decision, not simply a more expensive version of the same function.

Does Basalte run its own automation software?

No — Basalte keypads are the physical interface only. The automation logic, scenes, and schedules run on whichever platform (Crestron, Lutron, or KNX) is actually specified for the property.

How long is the lead time for Basalte hardware?

Longer than a standard platform keypad, since it's a specialist European import rather than a locally stocked item — worth factoring into project timelines during design rather than discovering it late.

Does the proximity sensor on Fibonacci work reliably in bright daylight?

Basalte's own documentation doesn't specify ambient-light limits for the proximity sensor, and this hasn't been independently verified against strong direct sunlight conditions specifically — worth a site-specific check during design for an entryway with significant natural light exposure, rather than assuming it behaves identically to an indoor installation.

Can Fibonacci and Sentido be mixed in the same home?

Yes — a common approach specifies Fibonacci at entry points and formal spaces where its finish is most visible, and Sentido in bedrooms and family spaces where the built-in temperature sensor is genuinely useful, all on the same underlying platform.

Does Agrima carry Basalte hardware in its own product catalogue?

Yes — Fibonacci and Sentido, in Cresnet, KNX, and generic variants, are listed in Agrima's own product catalogue as a standing brand partner, alongside Crestron, Lutron, KNX, and Black Nova.
