Apple Home

Once paired, your readings show up on your iPhone, iPad, and HomePod, and you can use them in automations. It's all local; nothing goes through a cloud.

Pairing

The bridge prints a pairing QR code and PIN to its log when it starts:

docker logs sigen-home-bridge

The same QR and code also live in the dashboard under Settings → Apple Home, so you can pair without the logs.

In the Home app: Add Accessory, scan the QR (or More Options to type the PIN, default 516-35-163). The bridge isn't Apple-certified, so the Home app calls it an uncertified accessory; tap Add Anyway. Pairing survives restarts and upgrades.

Reading the numbers

Here's the catch worth understanding up front. The Home app has no power sensor it will actually display, so the bridge borrows the ones it does. Each power reading rides in on a Temperature sensor (the only built-in type that shows a signed decimal), and battery charge rides in on a Humidity sensor. The ° and % symbols are just cosmetic; read the temperatures as power and the humidity as battery charge:

In the Home app	Actually means	Example
Solar Production	Solar output in kW	3.2° = generating 3.2 kW
Home Consumption	Home usage in kW	1.0° = using 1.0 kW
Grid Power	kW, + importing / − exporting	-1.1° = exporting 1.1 kW
Battery Power	kW, + charging / − discharging	-2.6° = discharging 2.6 kW
Battery Percent	Battery charge	31% = 31% charged

The readings land under Climate. The power sensors group into one Temperature tile (tap it to see each named reading) and the battery sits as a Humidity tile. A Battery service underneath flags low battery below 20%.

Use Apple Home for a glance and for automations; use the dashboard for the properly labelled view.

One gotcha: Fahrenheit homes

A Temperature sensor is shown in your home's temperature unit. If your Apple Home is set to Fahrenheit, it converts these values (4.5 shows as 40.1°F), so the number stops matching the kW. Set the Home app to Celsius to read them directly, or just use the dashboard.

Settings

You set all of it from Settings → Apple Home: the pairing QR and code, the bridge name, PIN, and port, a switch to show power in watts instead of kW (4500° instead of 4.5°), and an editable name for every sensor.

The name and unit are read when the bridge boots, so save and restart. And because Apple Home keeps the names it paired with, you'll need to remove and re-add the accessory to see new names.
