NodOn Zigbee Pilot Wire Heating Module Review: Smart Control for Pilot-Wire Electric Heating
The NodOn Zigbee Pilot Wire Heating Module (SIN-4-FP-21) is a concealed 230 V module that retrofits a pilot-wire electric heater with Zigbee control, letting a hub set the heater's pilot-wire orders, such as Comfort, Eco, Frost Protection and Off, automatically. It handles heaters up to 3680 W, meters the power and energy they use, and doubles as a Zigbee router because it is mains-powered. It needs a Zigbee coordinator, with Home Assistant supported through ZHA and Zigbee2MQTT, and has no Matter, Apple Home, Alexa, Google Home or SmartThings path, so it suits homes already built around Zigbee where pilot-wire heating is standard.
- Pilot-wire electric heaters
- Home Assistant and Zigbee2MQTT households
- Automating heating room by room
- Tracking the energy use of electric heating
Pros

- Handles heaters up to 3680 W at 230 V AC
- Built-in energy metering of the connected heater
- Doubles as a Zigbee router that strengthens the mesh
- Direct Zigbee binding with the NodOn Wall Switch, no hub needed for the basic modes
- Over-the-air firmware updates and power-off memory
- Home Assistant support through ZHA and Zigbee2MQTT
Cons
- Needs a Zigbee coordinator for automations, with no Wi-Fi radio
- Requires a neutral wire at the installation point
- For pilot-wire heaters only, with no dry contact mode
- No Google Home, Alexa, Apple Home, SmartThings or Matter support
- Panel installation needs the optional NodOn DIN Rail Box accessory
Who is the NodOn Zigbee Pilot Wire Heating Module for?
This is a module for anyone with an electric heater that uses a pilot wire, the control line common in French electric heating, who wants to drive it from a smart home system instead of a manual programmer. At 40 x 40 x 16.9 mm and 34 g it is a flush-mount module that hides in the existing wiring, and with the optional NodOn DIN Rail Box it can also live in the electrical panel. Because it is a Zigbee 3.0 device, it fits households that already run a coordinator, typically Home Assistant with ZHA or Zigbee2MQTT, rather than a Wi-Fi-only setup.
What the NodOn Zigbee Pilot Wire Heating Module offers
The module controls a heater rated up to 3680 W at 230 V AC, with a 16 A capacity, and drives its pilot-wire orders so a hub can set the room's heating mode on a schedule, on presence, or when a window opens. It also meters the power and energy the heater uses, which is what turns heating automation into measurable savings, and power-off memory restores its state after an outage. Being permanently powered, it acts as a Zigbee router that strengthens the mesh, and it takes over-the-air firmware updates. It can also be bound directly over Zigbee to the NodOn Wall Switch, which then sets the four basic modes (Comfort, Eco, Frost Protection and Off) with no hub involved. Overheating, overvoltage, overcurrent and overpower protection are built in, and its idle draw is under 1 W.
What to know before you buy
This is a Zigbee device with no Wi-Fi or Bluetooth radio, so it needs a compatible coordinator for anything beyond the wall switch binding. It requires a neutral wire at the installation point, and it is built for pilot-wire electric heaters: it has no dry-contact mode, so it cannot fire a boiler or open a gate, and it does no shutter control. Smart home support is narrow by design: Home Assistant works through ZHA and Zigbee2MQTT, while Google Home, Alexa, Apple Home, SmartThings and Matter are not supported. There is no button on the module itself, and panel installation needs the optional DIN Rail Box.
Is the NodOn Zigbee Pilot Wire Heating Module worth it?
For a pilot-wire electric heater, it packs the two things that usually force a bigger purchase, proper pilot-wire control and built-in energy metering, in a module that hides in the existing wiring and strengthens the Zigbee mesh at the same time. It is the practical pick for automating electric heating room by room in a home that already runs Zigbee and Home Assistant. Anyone who needs dry contacts for a boiler or gate, or wants an Apple Home or Matter path, should look at a multifunction or Matter relay instead.
Frequently asked questions
Does the NodOn Zigbee Pilot Wire Heating Module need a hub?
For automations, yes. It is a Zigbee 3.0 device with no Wi-Fi, so it needs a coordinator such as Home Assistant with ZHA or Zigbee2MQTT. Without a hub, it can still be bound directly to the NodOn Wall Switch to set Comfort, Eco, Frost Protection and Off.
Does it need a neutral wire?
Yes. It is powered from 230 V AC, so a neutral wire must be available where it is installed.
Can it control a boiler, gate or garage door?
No. The module is dedicated to pilot-wire electric heaters and offers no potential-free (dry contact) output and no shutter mode.
Does it measure energy use?
Yes. It has built-in energy monitoring for the connected heater, so its consumption can be tracked and used in automations in the hub.
Does it work with Alexa, Google Home, Apple Home or Matter?
No. It is not compatible with Alexa, Google Home, Apple Home, SmartThings or Matter. It works with Home Assistant through ZHA and Zigbee2MQTT.
How much heating power can it handle?
It is rated for resistive loads up to 3680 W at 230 V AC, with a 16 A capacity.
