Your water use in litres, live in Home Assistant.

Councils across Australia fit Taggle smart meters that usually broadcast your usage every hour. Plug in an RTL-SDR, point it at the street, and ha-taggle turns that signal into litres in Home Assistant, or any MQTT system.

Runs on a RTL-SDR

The same USB radio people use for aircraft and weather stations. Plug it into the computer running Home Assistant, or any Linux box with Docker, and it listens on 922 MHz. It only receives; nothing is ever sent to the meter.

RTL-SDR Blog V4 tested. A short 8 cm antenna near a window facing the street.

Home Assistant add-on

Guided install on Home Assistant OS. Sensors appear automatically once MQTT is set up.

Docker + MQTT

Prefer your own setup? Run the container and read litres from any MQTT broker.

AS YOU SCROLL

One card. Your whole day of water.

Step 1
Every hour, your meter checks in

The live dot pulses when a reading lands. Today's total counts up and the ring fills against your usual day.
Step 2
See when the water ran

Hour bars grow in one by one. The 6 pm shower-and-dinner peak lights up: 175 litres.
Step 3
Catch leaks early

If water never stops, overnight or all day, the card says so. Compare with your street, anonymously.

A few things to know

Does it work with my council?

Only one transmitter has been verified: Gladstone, QLD, on an owner-confirmed Elster (Honeywell) V100 with an RTL-SDR Blog V4. Other models and areas are unverified. Confirm Taggle is used at your property and check the transmitter label. NB-IoT transmitters are not supported; supported encrypted messages provide IDs and signal diagnostics only, no usage.

Is it legal / does it transmit?

ha-taggle is receive-only. It listens without connecting to or changing the meter; nothing is sent to the meter. Check your local laws before use. Privacy and legal guide.

Do I need Home Assistant?

Home Assistant is the documented dashboard route. The receiver passes messages through MQTT, so you can use your own MQTT system instead. The custom Home Assistant card is optional.

How accurate is it?

Updates are usually hourly. The transmitter sends a pulse counter, not your dial reading. Two aligned manual dial readings calibrate the litres per pulse and starting offset; another reading may be needed. Check the estimate against your physical dial. This is experimental, not billing-grade measurement.

What hardware?

The tested receiver is an RTL-SDR Blog V4, with a suitable 915–928 MHz antenna and a USB extension cable. You need an always-on Pi, mini PC or NAS running Home Assistant OS or Docker on Linux, with USB access, plus an MQTT broker. Supported architectures are amd64 and aarch64. Other receivers are unverified.
