An XDA Developers article published Oct. 26 says the ESP32-C6 is a practical choice for smart-home builds because one board supports Wi-Fi, Bluetooth Low Energy, Zigbee and Thread. Its low cost and compatibility with tools such as ESPHome and Zigbee2MQTT may reduce the need for separate radios, though setup and capabilities depend on the project.
The ESP32-C6 can run Wi-Fi, Bluetooth Low Energy and the 802.15.4 radio used by Zigbee and Thread, making it a candidate for smart-home projects that might otherwise need separate radio hardware. In an article published Oct. 26, XDA Developers contributor Samir Makwana described using the board for sensor and automation builds, while noting that it is not the right choice for every workload.
The C6 combines a 2.4GHz Wi-Fi radio and Bluetooth Low Energy with an 802.15.4 radio. The latter supports Zigbee and Thread, so a compatible project can use the board to connect to Wi-Fi while also communicating with a low-power mesh network. Makwana said that arrangement can avoid adding a separate radio adapter or wiring another board to the project.
That distinction matters when a device needs to join a home mesh rather than communicate only through a Wi-Fi router. Makwana contrasted the C6 with an ESP32-S3 board he used to map Wi-Fi coverage with ESPHome: the S3 sent data to Home Assistant over Wi-Fi, but did not provide the same built-in option to join a Zigbee or Thread network.
Makwana also reported that ESPHome and Zigbee2MQTT support the C6, which can make it easier to connect projects to a Home Assistant setup. The article says basic C6 development boards cost about the same as several Wi-Fi-only alternatives, but it does not provide a retailer, price survey or date-specific market comparison. The cost case is therefore an observation, not a guarantee for every board or market.

Why the ESP32-C6 Makes Sense for Smart Home Projects
One compact board combines Wi-Fi, Bluetooth Low Energy and the 802.15.4 radio used by Zigbee and Thread. For small sensors and automation nodes, that can leave more connection options open with less separate radio hardware.

01 / Radio flexibility
One board, several ways to connect
The ESP32-C6 pairs 2.4 GHz Wi-Fi and Bluetooth Low Energy with an 802.15.4 radio. Depending on the board and firmware, that radio can support Zigbee or Thread projects alongside Wi-Fi connectivity.
01 · Local network
Wi-Fi
Connect a project to a home network for data exchange and device integration.
02 · Low energy
Bluetooth LE
Bluetooth Low Energy adds another radio option for suitable setup and device workflows.
03 · Mesh radio
Zigbee or Thread
The shared 802.15.4 radio can make mesh-oriented builds possible without a separate radio on the project board.
02 / From idea to working device
Choose the network role before you build
Integrated radio hardware can simplify the parts list. Firmware and network configuration determine what the finished device can actually do.
Define the job
Sensor, switch, automation node, or another embedded task.
Pick the protocol
Decide whether the device needs Wi-Fi, Zigbee, Thread, or a combination.
Check support
Confirm board and firmware support in current ESPHome or Zigbee2MQTT documentation.
Configure the role
Plan any coordinator, border-router, or commissioning requirements.
03 / Fit by project
Where the C6 helps—and where to look elsewhere
The article presents the C6 as a practical option for modest smart-home builds, not a universal upgrade for every embedded workload.
| Project need | ESP32-C6 fit | What to keep in mind |
|---|---|---|
| Small sensor or automation node | ✓ Strong fit | Multiple radio options may reduce separate hardware. |
| Home Assistant integration | ✓ Reported support | Makwana reports support in ESPHome and Zigbee2MQTT; check setup details. |
| Thread border router or full hub | ~ Configuration dependent | Radio capability alone does not make a board a border router or hub. |
| Heavier processing task | ~ Assess separately | Makwana points to the ESP32-S3 for more demanding work, such as a Tailscale node. |
04 / Limits and evidence
A practical recommendation, with project caveats
What the article reports
XDA Developers contributor Samir Makwana describes using the C6 for smart-home builds and says ESPHome and Zigbee2MQTT support it. He contrasts it with separate equipment previously used for mesh connectivity.
What it does not establish
No independent benchmarks, power measurements, range tests, or detailed price survey are provided. Cost and ease depend on board, firmware, devices, and market.
Radio does not equal role
The hardware includes Thread-capable 802.15.4, but a specific network role depends on firmware and configuration. One setup is not guaranteed to perform every role at once.
Matter needs verification
The radios may make the C6 a possible starting point for Matter-related projects. Confirm commissioning support and the intended network role in the chosen software.
Traceability / Build path
From capability to connected project
Keep the decision chain visible: the radio is one part of the design; the software and network role complete it.

One Board for Multiple Smart-Home Radios
For hobbyists building sensors, switches and small automation nodes, integrating multiple radios can reduce the number of separate components to buy, wire and configure. A board that can connect over Wi-Fi for one project and use Zigbee or Thread in another also gives builders more room to change the design without replacing the hardware at the outset.
That flexibility may be useful for Matter-related projects. The article describes the C6 as a possible starting point for a Matter smart home because its radio capabilities include Wi-Fi and 802.15.4. However, the presence of compatible radios alone does not establish that every device or firmware configuration will support every Matter commissioning or network role. Builders still need to select and configure software appropriate to the intended device.
There is a practical limit: the C6 is aimed at relatively modest embedded tasks. Makwana says he would choose an ESP32-S3 for projects needing more processing capacity, citing a Tailscale node as an example. The C6’s appeal is radio flexibility and suitability for small smart-home devices, not a claim that it outperforms other boards across all uses.

From Separate Radios to a C6 Board
Makwana describes a previous approach in which a Wi-Fi-capable ESP32 handled a sensor or data task while separate equipment supplied mesh connectivity. For a Thread border router, he used a spare Raspberry Pi 4; for Zigbee, he relied on a separate coordinator. That meant checking available parts and setting up more than one device before starting some projects.
The ESP32-C6 changes that hardware equation by placing Wi-Fi, Bluetooth Low Energy and 802.15.4 on one chip. It does not mean every C6 board automatically becomes a border router or a complete smart-home hub. The board’s role depends on the firmware and network configuration. Makwana’s case is that the same hardware can support projects that would otherwise require a separate radio, and that a sensor can be designed with more than Wi-Fi in mind.
The article also distinguishes the C6 from ESP32 boards used with ESP-NOW, a communication method Makwana used in a mesh project. That network did not appear on his router’s interface, and moving to Zigbee or Thread would have required compatible hardware. The C6 can reduce that upfront hardware choice, though changing protocols later can still require firmware changes and reconfiguration.
Firmware and Project Limits Remain
The article does not provide independent benchmarks, power-consumption measurements, protocol range tests or a detailed price comparison. Its cost and ease-of-use assessments reflect Makwana’s experience; actual results can vary by development board, firmware, connected devices and regional pricing.
It is also not clear from the article which specific C6 firmware configurations were used for each Zigbee, Thread or Matter task. Although the hardware includes the relevant radio and the article reports support in ESPHome and Zigbee2MQTT, that does not mean one setup can perform every network role at once or that all features work without configuration. Readers should check the documentation for their chosen board, firmware and smart-home platform before designing around a particular capability.
Choose Firmware Before Building
For a new project, the next step is to identify whether the device needs Wi-Fi, Zigbee, Thread, or a combination, then confirm that the selected C6 board and firmware support that role. Builders connecting devices to Home Assistant should check current ESPHome or Zigbee2MQTT documentation and account for any required coordinator, border-router or commissioning setup.
For small sensors and automation nodes, the C6 may simplify prototyping by leaving several radio options open. Projects with heavier processing needs should be assessed separately; Makwana points to the ESP32-S3 as a better fit for some such tasks. The article offers a practical recommendation, not a report of a new product launch or a change in official platform support.
