Hoq Sensor

Keep every reading from your fridges, rooms and meters, with alerts when one drifts.

What it does

A feed holds readings from one thing that measures: a fridge probe, a room's temperature and humidity, a power meter, a motion sensor. Anything that can send a webhook can post to a feed with no key, using fields like temperature, humidity and battery. Devices that hold a key post batches of up to 5,000 readings, and a batch sent twice lands once.

You set rules per feed: above a value for so long, below a value for so long, or silent for so long. Rules run on the readings' own timestamps, so a sensor catching up after an outage raises the same alerts it would have raised live. Alerts go by email and to a webhook you choose, once when they open and once when they close.

The feed page shows live values and a chart for the last hour to the last 30 days, with min-max bands, rule lines and alert spans. Temperatures can show in Fahrenheit while the API keeps the stored unit.

Raw readings are kept 90 days by default, and you can set anything up to 10 years. After that, hourly summaries stay so the long charts still draw.

Specifications

Where readings come from	Any device or service that can send an HTTP POST or a webhook. A Hoq Devices box can also forward nearby Bluetooth sensors.
Keyless webhook	POST JSON or a form to /hook/{token}. Common names like temperature and humidity map to the feed's fields; add a timestamp and temperature_unit when needed.
Batches	Up to 5,000 readings per post. A batch is idempotent on its reference, so retries never double-count.
Rules	Above, below or silent, each held for a number of seconds, up to 30 days. Up to 32 rules per feed.
Alerts	Email and a webhook per rule. Each alert is sent once when it opens and once when it clears.
History	Live 60 seconds, or 1 hour, 6 hours, 24 hours, 7 days and 30 days, drawn with min-max bands.
Retention	Raw readings 90 days by default, adjustable from forever to 3,650 days. Hourly summaries are kept after the raw data goes.
Units	Celsius, Fahrenheit and Kelvin. A field can store one unit and show another.
Organizations	An organization can own feeds. Members view; admins and owners change rules and settings.

Features

14 features, all shipped. Listed from the product's code and documentation; each row shows the day it was last checked.

Feeds 4
Presets	Start a feed as a temperature probe, temperature and humidity, power meter, motion sensor or event log.
Pause and close	A paused feed refuses posts with 409 so the sender drops them instead of retrying.
Sources	The first post from a key or webhook makes a source; revoking it stops it for good.
Move between owners	Move a feed with its rules and alerts from you to an organization.

Ingest 3
Keyed API	POST /v1/feeds/{key}/readings with a sensor:post key.
Webhooks	Keyless /hook/{token} for Home Assistant and similar senders.
Bluetooth via Hoq Devices	A box with the sensor role forwards motion sensors and Bluetooth advertisements.

Alerts 4
Threshold rules	Above or below a value for a set time.
Silence rules	Alert when a feed stops reporting for a set time.
Email and webhook	Notices to the owner by email and to a webhook per rule.
Alert log	Every alert with its peak, last value, start and end.

Viewing 3
Status cards	Dashboard cards with latest values and ok, alert, quiet or no-data status.
Charts	Live and 1 hour to 30 days, with bands, rule lines and alert spans; hide a series from the legend.
Motion marks	Mark a pose and ask how far a thing has tilted or moved since, in degrees and plain words.

Works with

Hoq DevicesA Hoq Devices box with the sensor role reads nearby Bluetooth sensors and posts them here.
Hoq AssetsA thing in Hoq Assets can carry a Hoq Sensor feed.
Hoq ID and platformAPI keys come from Hoq ID with the sensor:post, sensor:read and sensor:manage scopes.

Your data

Where it is kept	Recent readings are in Hoq Sensor's database; closed hours roll into gzipped NDJSON files on the Sensor server.
Getting it out	The JSON API returns readings, history, rules and alerts. No CSV export is built.
If you leave	Closing a feed stops new readings. Account closing is not documented.
