The hidden wire your thermostat needs, but many homes don’t have. It has kept millions of homeowners out of the smart thermostat market for years. CliQ is the smart thermostat made for homes without a C-wire. Easy install. Smart comfort. No rewiring needed.
Most smart thermostats need a C-wire to stay connected to Wi-Fi. Tens of millions of US homes don't have one. Here's what that leaves you with.
Your thermostat talks to your furnace through wires in the wall. Most carry signals. The C-wire is the one that carries continuous power.
Homes built before roughly 2010 shipped with a two-wire thermostat setup. No C-wire was ever pulled through the wall. It simply is not there.
A smart thermostat has to stay connected to Wi-Fi every few minutes to keep working. That constant polling burns power continuously. Without a C-wire feeding it steady house power, most smart thermostats go dark — or try to steal power from your HVAC circuit and cause problems.
Some competitors offer a C-wire adapter kit. It is extra hardware, extra cost, extra installation risk, and often voids your HVAC warranty. It is a patch, not a fix.
Tens of millions of US homeowners tried to upgrade and hit a wall. Their house just does not have the wire that modern competitors require.
The entire smart thermostat category decided that tens of millions of American homes simply were not the target market. If your house does not have the right wiring, you are out.
CliQ's architecture doesn't create a C-wire requirement in the first place. The wall device doesn't carry the Wi-Fi burden — so it doesn't need continuous house power to do it. No workaround. No adapter. No surprises when you open the box.
Most smart thermostats are single-device systems — one unit on the wall managing everything: HVAC control, Wi-Fi, cloud sync, app updates. Staying connected to Wi-Fi means polling the network every few minutes to stay alive. That constant draw is exactly why those thermostats need a C-wire providing steady house power.
CliQ is engineered differently. The connectivity burden doesn't sit on the thermostat. The wall device communicates via low-power radio — not Wi-Fi — so it never needs to maintain a constant internet connection or draw steady power to do it. The C-wire requirement disappears with the architecture that created it.
CliQ's architecture doesn't create a C-wire requirement in the first place. Other thermostats need house power because they run Wi-Fi directly on the wall unit. CliQ separates that burden — so the wall device stays low-power and the C-wire question never comes up.
CliQ ships with a mounting screw kit, labeled wiring stickers, a hub, and a QR code welcome card. You do not need to buy anything else. Certainly not a C-wire adapter.

The questions homeowners ask before they realize CliQ makes all of them irrelevant.
A C-wire, or common wire, is the wire in your thermostat wiring that provides continuous 24-volt AC power from your HVAC system to your thermostat. Unlike the other wires in a typical thermostat setup, which carry control signals, the C-wire delivers steady power so the thermostat can stay on and connected without interruption.
Most smart thermostats require a C-wire because they need continuous power to maintain a Wi-Fi connection. If your home doesn't have one — which is common in homes built before 2010 — you're typically left with three options: hire an electrician to run a new wire, buy an adapter kit, or choose a thermostat that doesn't require one. CliQ is built from the ground up to work without a C-wire.
Most smart thermostats run Wi-Fi directly on the wall unit, which requires constant power — hence the C-wire. CliQ uses a different architecture: the wall device communicates via low-power radio to a hub, instead of connecting directly to Wi-Fi. Because the wall unit doesn't carry the Wi-Fi burden, it doesn't need steady house power. The C-wire requirement disappears with the design that created it.
CliQ is designed specifically for homes without a C-wire and requires no adapter or additional wiring. Some other manufacturers offer workarounds — like C-wire adapter kits or power-stealing modes — but these add cost, installation complexity, and can cause HVAC issues. CliQ eliminates the requirement entirely rather than working around it.
With CliQ, yes. Because there's no C-wire requirement, you connect to the same two wires your existing thermostat already uses. No new wiring, no electrician, no tools required for most installs. The CliQ app walks you through the process step by step, and most homeowners are done in under 30 minutes.
Installation takes under a minute with compatible wall plates. App download and registration additional.
