Making your old water meter smart
You can wirelessly read your analog water meter using WiFi, making it a smart device. Transforming your analogue water meter into a smart water meter allows you to remotely access and track your water consumption through a user-friendly watter consumption overview. By doing so, you can conserve water, which contributes to environmental sustainability. The recommended solution for achieving this is the Smart Gateways Water Meter Gateway. By attaching a sensor to the water meter, it records water usage and transmits the data to Home Assistant.
The Smart Gateways Water Meter Gateway comes in two versions:
- Version A: For water meters with a metal plate or nfc chip on a rotating wheel
- VERSION B: For water meters with a slot for a magnetic reed-sensor (mostly used in Belgium, Great Britain and Australia)

In this post, I will guide you on creating a comprehensive dashboard that displays all the values from the Smart Gateways Water Meter Gateway. The dashboard not only presents consumption and costs per day, week, month, and year but also empowers you to make your water meter intelligent by utilizing the Smart Gateways Water Meter Dashboard for Home Assistant. Actually Smart Gateways was the first company providing an off the shelf solution that could make your analogue water meter smart. A few years later the Smart Watermeter Gateway is used all over the world to get insights into water consumption.
The Smart Gateways Watermeter Dashboard for Home Assistant is the perfect complement to Home Assistant’s existing energy dashboard. Of course you can use both dashboards next to each other. Just pick the dashboard you like the most.

Water Costs
It is possible to enter the costs for water consumption into the dashboard. There are 3 values to be filled in. You can find those values in the lower right corner. Please note that these costs are based on water consumption in the Netherlands. You can ask your water company for the prices.
- Water – Belasting: Tax on water (per liter)
- Water – Prijs per liter: Price per liter
- Water – Vastrecht: Fixed price you have to pay per year to the water company
Prices have to be filled in in Liters. Home Assistant works with cubic meters so you have to divide the values by 1000. Amounts are very small because water prices are low in the Netherlands. You can remove the prices from the dashboard if you don’t use them.
