Appliance Auto Notify¶

Automatic notifications for household appliances in Home Assistant, with no automations or YAML.

When a dishwasher, washing machine, oven or other appliance starts a cycle, you're told it started, your phone shows a Live Activity with progress and time remaining while it runs, and you're told when it finishes.

This is an early version to try with real appliances. It supports Bosch, Neff and Siemens appliances connected with the Home Assistant Home Connect integration, in English only. Any other appliance can be added by hand if it has a power monitor, such as a smart plug.

What You Need¶

• Home Assistant 2026.7 or later
• An appliance set up with the Home Connect integration, or one with a power sensor
• Supernotify, installed from HACS, for Live Activities and for anything beyond a plain notification
• Home Assistant app installed on an Apple mobile device, minimum iOS/iPadOS 17.2

Without Supernotify, it only sends a start and an end notification, to every phone with the Home Assistant app unless you choose other notify entities.

Install¶

1. Use the button above, or in HACS add https://github.com/rhizomatics/appliances_autonotify as a custom repository of type Integration, then install Appliance Auto Notify and restart Home Assistant
2. In Settings, Devices & services, choose Add integration and pick Appliance Auto Notify
3. Leave Set up appliances automatically on, and submit

That's all. Every Home Connect appliance is set up straight away, and so is any you add later. Each is listed on the integration's page, alongside Automatic discovery, and notifies with no further settings.

To stop the notifications for an appliance, disable it rather than delete it, since a deleted appliance is found and set up again.

Choosing Appliances Yourself¶

Turn Set up appliances automatically off, on the first screen or later from the settings of Automatic discovery, and appliances are instead offered as Discovered on the Devices & services page. Choose Add to set one up, or Ignore on any you don't want.

Power Monitored Appliances¶

An appliance with no supported integration can be added if a sensor measures the power it draws.

1. On the integration's page, choose Add service
2. Give the appliance a name, and choose its power sensor

Raise the grace period for appliances that pause mid-cycle, such as a washing machine soaking.

Settings¶

Nothing needs changing for notifications to work. Each appliance on the integration's page has settings: Notify start and Notify end switches, both on by default, for an oven a Notify phases switch, also on by default, a Notify progress switch, off by default, with Supernotify a Dashboard to open when a notification or the Live Activity is tapped, and then three sections that start closed. With Notify start or Notify end off, that notification isn't sent, but the Live Activity is still opened and closed, silently and on phones only. The dashboard is a choice of those in Home Assistant, never a URL to type in, so a notification can't be made to open anything else.

What Gets Sent¶

Pausing and resuming an appliance counts as the same cycle. An appliance that is switched off, like an oven, counts as finished.

Oven Pre-heating¶

An oven with no timer set has no progress to report, so while it warms up, on any program, the bar is its temperature as a percentage of the one it's set to, and the message is the two of them, such as "Pre-heating, 150 of 200°C", or "Fast pre-heat" in place of "Pre-heating" while that is on.

Once the oven is as hot as asked for, or reports that pre-heating is finished, "Oven is pre-heated" is sent everywhere as a notification of its own, unless Notify phases is off. The Live Activity stays until the oven is switched off, and goes straight on to the program and the temperature, such as "Pizza setting, 200°C", updated whenever the temperature has moved by 5 degrees. From then on the oven isn't taken to be warming up again, however its temperature wanders, until it has been off. With a timer set, the bar then goes on to the progress of the program.

Icons¶

The icon of a notification follows the type of appliance: dishwasher, washer, dryer, washer dryer, oven, hob, hood, coffee maker, cleaning robot or air conditioner. A power monitored appliance has none to go by, so its name is used instead, as in "Washer" or "Kettle".

Known Limits¶

• Pre-heating is the only phase of a cycle there is to tell of, since Home Connect reports none for a dishwasher or washer, such as pre-wash or rinse

• If the appliance never reports the end of its cycle, the Live Activity stays on the phone until dismissed

• If Home Assistant restarts mid-cycle, the end is still notified and the Live Activity closed
• Progress, time remaining and the program are only shown where the appliance reports them, so never for a power monitored appliance
• If Home Assistant restarts while an oven is on, it isn't shown as pre-heating, since there's no knowing whether it has been up to heat, only with its program and temperature
• An oven with no timer set reports its progress as 100%, so that is what the bar shows once it's up to heat

Known Issues¶

Both of these have been seen on an iPhone, and neither has a confirmed cause yet.

Progress bar behind the appliance¶

The progress bar of the Live Activity can fall well behind, such as showing 40% while the appliance is at 74%.

The likely cause is iOS. Progress is sent with silent: true, so that the phone doesn't alert every 10%, and the Companion App sends silent updates at a lower priority, which iOS may delay, batch or drop. This is a theory, since it hasn't been tested by sending the updates without silent.

Turning on Notify progress sends each update as an ordinary notification, without silent, so is worth trying if the bar matters more than the interruptions.

Seconds shown as dashes¶

The time remaining sometimes has dashes in place of the seconds, such as 52:-- or 1:30:--, on the Lock Screen while the Dynamic Island shows a full countdown at the same moment.

The same finish time is sent however it ends up shown, and the Companion App has no setting for the format of the timer, so this is down to the phone. The likely reason is that the Lock Screen is redrawn less often while it's dimmed or always-on, so drops the seconds. This is also a theory, and nothing has been found that changes it.
