Each page in a schedule block, and each rule that adds its page to the rotation, has a "skip in slow mode" checkbox. While slow mode is on those pages are left out of the rotation; when none of the block's pages are left, the chosen page is shown. The rotation keeps its own timers. Schedule format version 5; version 4 is converted when read and stored again in version 5 on the next save. Version 2.18.0. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>

# Home Assistant
|
|
|
|
[← Back to the README](../README.md)
|
|
|
|
The ESP32 connects to Home Assistant in two ways:
|
|
|
|
- **MQTT** (with discovery): the display's own switches, dropdowns, sensors and buttons.
|
|
Broker, user and password are in the web UI, Home Assistant tab (an empty broker uses
|
|
`secrets.h`). Changing them restarts the ESP32.
|
|
- **REST API**: values of any entity for the dynamic pages and the trigger rules. Set the
|
|
URL (empty: `http://<broker>:8123`, plain http only, use the IP address) and a
|
|
long-lived access token (Home Assistant, your profile, Security tab) in the same tab.
|
|
|
|
## Entities
|
|
|
|
- `FlipDot Display Power` switch: off clears the display and cuts power through the relay.
|
|
- `FlipDot Display Mode` dropdown: what is shown during the day, a dynamic page ("Clock"
|
|
first) or one of the bitmaps (the same choice as in the web UI).
|
|
- `FlipDot Display Off image` dropdown: what is left on the dots when the display
|
|
switches off (at night or with the Power switch): blank or one of the bitmaps.
|
|
- `FlipDot Display IP` sensor: the ESP32's IP address.
|
|
- `FlipDot Display Stopwatch` switch and `FlipDot Display Stopwatch reset` button: the
|
|
stopwatch of the dynamic pages.
|
|
- `FlipDot Display Shown page` sensor: what the display shows now (schedule, rule or
|
|
chosen page). `FlipDot Display Back to schedule` button: ends a page chosen by hand.
|
|
- `FlipDot Display Slow mode` switch and `FlipDot Display Slow mode interval` dropdown
|
|
(`1 minute` ... `60 minutes`): the display only changes at those times, on the clock, and
|
|
is switched off in between (less noise, e.g. in the evening with an automation). Rules
|
|
with "show at once in slow mode" still show their page right away; pages with "skip in
|
|
slow mode" are left out of the rotation.
|
|
- `FlipDot Display Firmware` sensor: version and health, e.g. `2.7.2, ok, 0 crashes, recovery ok`.
|
|
- `FlipDot Display Recovery` button: restarts into the [recovery app](recovery.md) for 10
|
|
minutes.
|
|
|
|
The unique ids of these entities never change, so automations and dashboards keep working
|
|
after firmware updates.
|
|
|
|
## Values on dynamic pages
|
|
|
|
A Home Assistant value element on a [page](pages.md) shows an entity's state or one of
|
|
its attributes, as a number (multiplier, decimals, auto unit, without minus sign), a
|
|
duration, a time from a timestamp, or with own texts per state (see the
|
|
[web UI](web-ui.md#pages)).
|
|
|
|
**Home Assistant values** on the shown page are read every minute, one entity at a time,
|
|
by a task of their own (on the ESP32's other core), so a slow or unreachable Home
|
|
Assistant never holds up the display or the web UI. An unknown or unreachable value shows
|
|
`--`. The display only changes
|
|
when the shown text changes, so round values with the decimals setting.
|
|
|
|
## Rules
|
|
|
|
The [schedule](web-ui.md#schedule) can bring a page to the front from a Home Assistant
|
|
state, e.g. the 3D printer page while `sensor.mainsailos_current_print_state` is
|
|
`printing`. Each rule is read at its own interval; when Home Assistant can't be reached it
|
|
is read once a minute at most, so the display keeps running.
|
|
|
|
## Weather forecast
|
|
|
|
Weather entities have no forecast attribute anymore (since Home Assistant 2024.3); the
|
|
forecast comes from the `weather.get_forecasts` action. The **Verwachting** page reads it
|
|
from a template sensor that keeps the next days as an attribute. Add to
|
|
`configuration.yaml` (and restart Home Assistant, or reload the template entities):
|
|
|
|
```yaml
|
|
template:
|
|
- trigger:
|
|
- trigger: time_pattern
|
|
minutes: /30
|
|
- trigger: homeassistant
|
|
event: start
|
|
action:
|
|
- action: weather.get_forecasts
|
|
data: { type: daily }
|
|
target: { entity_id: weather.knmi_home }
|
|
response_variable: f
|
|
sensor:
|
|
- name: Weer verwachting
|
|
unique_id: weer_verwachting
|
|
state: "{{ f['weather.knmi_home'].forecast[0].condition }}"
|
|
attributes:
|
|
forecast: "{{ f['weather.knmi_home'].forecast[:4] }}"
|
|
```
|
|
|
|
The page then reads `sensor.weer_verwachting` with attribute paths: `forecast.0` is today,
|
|
`forecast.1` tomorrow, `forecast.2` the day after, e.g. `forecast.1.condition` (chooses the icon `weer7 <condition>`,
|
|
7 x 7 dots), `forecast.1.temperature` (max) and `forecast.1.templow` (min). The weekdays
|
|
are Date elements with a day offset. Use another weather entity by replacing
|
|
`weather.knmi_home` in the YAML (and on the page, for today's icon and temperature).
|
|
|
|
## Plex and Tautulli
|
|
|
|
The **Plex** page (in [examples/home-pages.json](../examples/home-pages.json)) uses Home
|
|
Assistant's Plex and Tautulli integrations, no extra firmware:
|
|
|
|
- `sensor.plex_server` (Plex, named after your server): how many are watching.
|
|
- `sensor.{plex_user}_state` (Tautulli, per user): `playing`, `paused`, ... chooses the icon
|
|
(icons `plex playing`, `plex paused`, `plex buffering`).
|
|
- `sensor.{plex_user}_full_title` and `sensor.{plex_user}_progress` (Tautulli, per user):
|
|
the title and the progress bar. Home Assistant creates these disabled: enable them on
|
|
the Tautulli user's device in Home Assistant.
|
|
|
|
`{plex_user}` is the Plex user set in the web UI (Home Assistant tab), written the way Home
|
|
Assistant puts it in entity ids (`MangaValk` -> `mangavalk`). A rule (Schedule tab) adds
|
|
the page to the rotation while `sensor.plex_server` is above 0.
