Our products run 100% locally on your own network, with software that is fully open source. Every product is designed, developed and built in the Netherlands.
SmartHomeShop.io builds smart home products for people 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.

| WaterMeterKit | Tracks a compatible analog water meter in Home Assistant. | Magnetic water meter sensing, absolute meter totals, temperature and humidity, WiFi, USB-C power. | Repo / Docs / Product |
| WaterFlowKit | Measures flow rate, total usage and water temperature on individual pipes. | Up to four flow inputs on v2, multiple YF-series sensor sizes, WiFi/Ethernet firmware, local and app-sync variants. | Repo / Docs / Product |
Each hardware revision has its own firmware folder, so the configuration that matches your device stays visible. The revisions differ in more than looks, which is why they are listed separately.
| Product | Presence | Air quality | Network | Voice | Links |
|---|---|---|---|---|---|
| UltimateSensor v1 | LD2450 mmWave tracking + PIR | CO2, temperature, humidity, lux, VOC/NOx, optional SPS30 particulate matter | WiFi, Ethernet, PoE | - | Repo / Docs / Product |
| UltimateSensor v2 | LD2412 presence + PIR, optional LD2450 or LD2460 multi-target tracking | CO2, temperature, humidity, lux, VOC/NOx, optional SPS30 particulate matter | WiFi, Ethernet, PoE | Microphone and speaker for Home Assistant Voice | Repo / Docs / Product |
| UltimateSensor Mini v1 | LD2450 mmWave tracking | CO2, temperature, humidity, lux, VOC/NOx, optional SPS30 particulate matter | WiFi | Microphone and speaker for Home Assistant Voice | Repo / Docs / Product |
| UltimateSensor Mini v2 | LD2412 presence, optional LD2450 or LD2460 multi-target tracking | CO2, temperature, humidity, lux, VOC/NOx, optional SPS30 particulate matter | WiFi, Ethernet, Thread | - | Repo / Docs / Product |

Looking for voice? The microphone and speaker moved between revisions. On the Mini they are part of v1 and not of v2; on the full UltimateSensor it is the other way around, so v2 is the one that talks. Every revision measures the same air quality, so pick the one whose presence detection and voice support match what you want.
- 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 or Thread 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.
