For the
HomeWizard P1 dongle (also sold as the
HomeWizard Wi-Fi P1 Meter), the frequency at which it
updates and sends data depends on
the smart meter it’s connected to — not a fixed 5 seconds by default:
Data Update Frequency
- Electricity data (power): updated every second on most modern smart meters (DSMR 5.0 or equivalent), so you effectively get near-real-time readings (≈1 Hz).
- Gas data: typically updated every 5 minutes on many meters (older meters might only update hourly).
What “sending data” means
The P1 dongle
reads the smart meter’s P1 port at whatever update interval the meter itself uses — every second for electrical values on newer DSMR-compliant meters — and then
makes that data available over Wi-Fi (e.g., to the HomeWizard app or a local API).
So:
- The smart meter outputs data roughly every second (for power), and the dongle makes that available on your network.
- It doesn’t only push data every 5 seconds by itself — it reflects whatever the meter sends and you can poll the local API as often as you like (while respecting modest rate limits).
🛠 Polling/Requests
If you’re querying the local API (e.g., from Home Assistant), clients sometimes poll every
5 seconds for updates. That’s a configuration choice in the client/integration, not a restriction of the P1 dongle itself.
In summary:
✔ Electrical power data updates ~
every second
✔ Gas data ~
every 5 minutes (meter-dependent)
✔ 5 s polling often used by software clients, but not a strict sending interval of the dongle itself.
If you need specifics for your exact smart meter model, those update intervals can vary slightly — let me know and I can help check that too.
