Description The Seeed Studio IoT Button V2 is a compact smart button for Home Assistant, ESPHome automation and Zigbee/ZHA control. Built around the ESP32-C6, this IoT Button combines 2.4GHz Wi-Fi, Zigbee capability, a rechargeable 18650 battery design, RGB status feedback and USB-C charging in a small enclosure with a stickable bracket. This IoT Button is useful when a smart home needs a physical trigger that is easier than opening an app. It can start Home Assistant scenes, toggle lights, control automations, trigger notifications or act as a desk-side programmable button. For Zigbee deployments, it can be paired through a compatible coordinator such as the Home Assistant Connect ZBT-1. The official firmware path supports ESPHome over Wi-Fi and a Zigbee firmware workflow for ZHA. With single click, double click and long-press style actions, the Seeed Studio IoT Button V2 gives Home Assistant users a flexible wall, desk or handheld control point for repeatable automation projects. Features ESP32-C6 smart button platform: combines an efficient RISC-V MCU with wireless connectivity for local automation projects. Home Assistant ready: designed for ESPHome and Zigbee/ZHA integration workflows documented by Seeed Studio. Flexible button events: supports single click, double click and long-press actions for scene control, device toggles and alerts. RGB status LED: provides visual event and device-state feedback during pairing, control and automation testing. USB-C charging: rechargeable power design with a 3.6V Li-ion 18650 battery configuration. Stickable bracket: mount the IoT Button near a doorway, desk, workbench, appliance or demo station. OTA firmware updates: supports firmware maintenance without repeatedly opening the enclosure. Zigbee option for local control: suitable for low-power smart-home button deployments when paired with a Zigbee network.

Product List Seeed Studio IoT Button V2 x1 Stickable Bracket x1 Other Content Hardware overview: the IoT Button enclosure keeps the large button surface, RGB feedback and internal control board in a compact shape that can sit on a table or mount with the included bracket. This IoT Button format is intentionally simple, so users can place the IoT Button where a physical automation trigger is actually needed. Button and indicator layout: the official guide identifies the button, indicator LEDs and charging-related feedback so users can tell pairing, charging and control states apart. ESPHome workflow: the ESPHome path is intended for Home Assistant users who want YAML-defined actions over Wi-Fi. It is a good fit for scene control, reminders and custom dashboard automations. Zigbee workflow: with Zigbee firmware, the IoT Button can join a Home Assistant ZHA network and expose button-event endpoints for local automations. In this mode, the IoT Button behaves like a local control endpoint instead of a cloud-dependent remote.
