Device Enclosure — Important Notice ​

The WaterMeterKit enclosure (the main unit) is not waterproof or moisture-resistant. The device contains sensitive electronics and must be protected from water and excessive humidity.

⚠️ Warranty Exclusion: Damage caused by water ingress or moisture is not covered by warranty.

Suitable Installation Locations ​

  • ✅ Dry basements and cellars
  • ✅ Dry crawl spaces
  • ✅ Indoor utility cabinets / meter cupboards
  • ✅ Outdoor water meter pits — only if dry and protected (see tips below)

Locations to Avoid ​

  • ❌ Areas where water can drip or splash onto the device
  • ❌ Flooded or regularly wet areas
  • ❌ Unprotected outdoor locations exposed to rain
  • ❌ Areas with constant condensation dripping onto the device

Outdoor Water Meter Pits ​

Many water meters are installed in underground pits or enclosures outside. These can be challenging environments:

💡 Option 1: If the pit is dry and well-sealed, you can install the WaterMeterKit inside, but monitor for moisture buildup.

💡 Option 2: Install the WaterMeterKit in a separate weatherproof enclosure (IP65+) inside the pit.

💡 Option 3: Mount the WaterMeterKit outside the pit in a dry location (e.g., garage, shed), and run only the sensor cable into the pit to reach the water meter.

Water Sensor — Important Notice ​

The water sensor included with the WaterMeterKit is only lightly moisture-resistant. It is designed for typical water meter cabinet conditions but is not suitable for permanently humid environments.

⚠️ Warranty Exclusion: Damage to the water sensor caused by excessive moisture or permanent humidity is not covered by warranty.

Protecting Your Sensor ​

  • ✅ Normal water meter cabinet conditions are fine
  • ✅ Occasional condensation is acceptable
  • ❌ Do not install in constantly wet or flooded areas
  • ❌ Do not submerge the sensor in water
  • ❌ Avoid areas with constant high humidity (>80% RH)

Sensor Cable ​

The sensor cable is 3 meters long and is permanently attached to the WaterMeterKit (screw terminal connection). Extending it beyond this length is not recommended due to voltage drop causing unreliable readings.

⚠️ Warranty Exclusion: Any sensor cable modifications or extensions are at your own risk and not covered by warranty.

👉 See Installation Guide for details on disconnecting and cable limitations.

Replacement Sensors ​

The WaterMeterKit has a screw terminal connection for the sensor cable. If your water sensor needs to be replaced, please contact us:

Third-Party Modifications ​

The WaterMeterKit uses open-source ESPHome firmware, making it fully customizable.

What's Covered ​

✅ Manufacturing defects in the WaterMeterKit hardware
✅ Firmware issues with the official SmartHomeShop firmware
✅ Component failures under normal use

What's Not Covered ​

We cannot provide warranty or support for:

  • 🔧 Custom firmware modifications or third-party firmware
  • 🔧 Hardware modifications (soldering, component swaps)
  • 🔧 Software changes that cause the device to malfunction
  • 🔧 Configuration changes that deviate from our documentation
  • 🔧 Damage from improper power supply (using non-standard voltages)

Tinkerers welcome! We love that our products are built on open platforms like ESPHome. Feel free to experiment and customize — just know that once you modify the hardware or flash custom firmware, you're in DIY territory. Our Discord community is a great place to get help from fellow enthusiasts!
