Heiman HS9MS-E

Compatibility

Compatible with EpiSensor Edge over Zigbee.

Pair it with the Zigbee radio on an EpiSensor Gateway. Edge reads it locally on the Gateway.

Edge reads 25 values from it, listed under Interface.

Specifications

The camera works over Wi-Fi, not Zigbee. The sensor is given a Wi-Fi network, a password and a server address over Zigbee, with a second candidate network and address alongside, and it reports whether each Wi-Fi and server connection is up. Pictures are taken on command, with a picture count of 1 to 20 and a quality setting from 0 to 100, and a test command checks the camera, Wi-Fi and server connection together.^1, 2

Power

Alarms

Motion, tamper and low battery as IAS zone alarms¹

Camera

Pictures on command, 1 to 20 per request, quality 0 to 100¹

Camera link

Wi-Fi to a configured server, with a primary and a candidate network¹

Wi-Fi signal

RSSI reported from -127 to 127¹

Zigbee model ID

HS9MS-E¹

Where it is used

• Motion in offices and back rooms, to compare heating, cooling and lighting run hours with the hours a space is actually used.

  HVAC energy monitoring for commercial buildings

• After-hours checks in stores and plant rooms, where a picture on demand shows what triggered the sensor, if pictures to a Wi-Fi server are acceptable on the site.

Interface

Readings and settings, with units and ranges where Heiman publishes them. R readable, R·W readable and writable, W writable only.¹

The light level is passed on as the device reports it in the standard illuminance cluster. The Zigbee Cluster Library defines that attribute as 10,000 × log10(lux) + 1, and no conversion is applied, so check the reading against a lux meter before you use it as lux.^1, 3

The Wi-Fi SSID, password and server address, current and candidate, are text attributes in Heiman's manufacturer cluster. They can be written and read back over Zigbee.¹

Taking a picture and running the connection test are commands, not stored values, so they never appear in the reported state.²

Setup

1. Open pairing in Edge

   In Edge, open pairing on the Gateway’s Zigbee network. The Gateway accepts new devices while pairing is open.

2. Power it and start pairing

   Fit the battery and put the sensor into pairing mode as its instruction card describes.

3. Confirm the join

   Check that Edge identifies it as Heiman HS9MS-E, and that motion, battery and ambient light appear.¹

4. Set sensitivity and arming

   Set the PIR sensitivity to low, medium or high and arm the sensor. Leave the Wi-Fi settings empty if you do not use the camera.¹

5. Check motion and light

   Walk through the area and confirm motion changes in Edge. Compare the ambient light reading with a lux meter before relying on it as lux.³

Common questions

Does Edge need the camera or Wi-Fi to read motion?

No. Motion, tamper, battery and light level all arrive over Zigbee. The Wi-Fi settings only matter if you use the camera.¹

Is the Wi-Fi password visible over Zigbee?

Yes. The current and candidate Wi-Fi passwords are readable text attributes in Heiman's manufacturer cluster. Anyone with access to the Zigbee coordinator can read them back, so leave the camera's Wi-Fi unconfigured if you do not use it.¹

Is the ambient light reading in lux?

Not necessarily. It is the raw value of the standard illuminance attribute, which the Zigbee Cluster Library defines as 10,000 × log10(lux) + 1, and it is passed on without conversion. Check it against a lux meter first.^1, 3
