SmartHomeShop.io builds smart home products for users who want reliable sensor data in Home Assistant without a mandatory cloud account or subscription. Our devices are designed around ESPHome, local control, OTA firmware updates and practical installation guides.
Most firmware repositories contain production ESPHome packages, hardware-specific YAML files, changelogs and ESP Web Tools manifests. You can use the factory firmware, switch supported devices between WiFi and Ethernet variants, or adopt the device in ESPHome when you want to customize the configuration yourself.

- Factory firmware: flash or update supported devices from the SmartHomeShop firmware page with ESP Web Tools.
- ESPHome packages: use the YAML packages in each product repository when you want to manage firmware from your own ESPHome dashboard.
- Network variants: supported products provide WiFi, Ethernet and sometimes PoE-oriented builds. Some repositories also include SmartHomeShop App sync variants next to the fully local firmware.
- Hardware revisions: product repositories keep separate folders for each hardware revision, so the matching configuration stays visible and auditable.
- Changelogs: firmware-facing release notes live in the product repositories, usually in
CHANGELOG.mdand GitHub Releases.
