Installation and operation

---

Installation

The housing is intended to be installed inside or outside a building but it must be protected from vertical water spray and direct sunlight. The housing can be screwed, or binded with double sided tape, but notice that it also can be used with various DIN rail adapter.

Radio propagation

In order for the sensor to operate correctly, the number of obstacles should be limited in order to avoid excessive radio wave attenuation. It is also important to place the sensor as high as possible. Notice that in the case of usage on roof windows the sensor may not be binded vertically, but even if the sensor is not in the best position, the upper situation (on the roof) of the sensor should ensure good results.

Autonomy

The information in the table below represents how long the battery can last. It is  based on the default configuration at ambient temperature (+25°C) within the optimal operating range of the sensor via a LoRaWAN network (one uplink frame), when the spreading factor used is SF12.

The disposable battery has a 3.6Ah capacity, of which 85% is used.

Human Machine Interface

---

The SkyDome sensor has a buzzer that allows it to “communicate” with the user.

A reed switch is available under the sticker "ILS". It is possible to use a magnet to activate it and makes specific actions on the sensor (Switch off, switch on, Re-associtation…). When the reed switch is activated, the buzzer rings quickly.

To Start-up the device, it is necessary to put a magnet on the  side of the sensor during one second (at the left side). The buzzer rings quickly during this step. After this second, the buzzer stops and rings slowly until the association is done.

To switch off the device, use the same way by putting the magnet during 5 seconds. After this amount of time, the device rings 5 times slowly.

The table below describes the actions to be performed on the reed switch to disable or enable the storage mode.

Action	Magnet	Buzzer
Switch ON (disable storage mode)	1 second
Switch OFF (enable storage mode)	5 seconds

When the sensor is trying to associate with a network, it emits the following sound:

Once the association is completed, the buzzer makes the following sound:

A reed switch (or magnetic switch) is available. A magnet can be used to activate it and perform specific actions on the sensor (switch off, switch on, reassociation…).

• Configuration: "void" frames are sent every minute for 10 minutes.

Standard reports are disabled in this mode.

Configuration mode
Way to trigger it	One passage of the magnet near the reed switch or specific ZCL command
Way to stop it	Another passage of the magnet or specific ZCL command
Effects on the sensor
Duration	The configuration mode lasts 10 minutes

• A reassociation procedure can be requested if no downlink frame is received by the sensor during a given periodicity (4 days by default) or if a given number (100 by default) is reached or in case of failure (no acknowledgement received) by sending an applicative frame to the sensor or via the sensor’s IHM.

The sensor keeps the AppEUi and DevAddr configured, Confirmed/Unconfirmed configuration and all applicative configurations. However, LoRaWAN configurations (channel, data rate…) are lost

ReAssociation Mode
Way to trigger it	Three passages of the magnet near the reed switch or ZCL command from LoRaWAN cluster.
Effects on the sensor

• A factory reset is available on Watteco’s sensors. It deletes all the applicative settings saved in the flash memory (i.e. configured batches and reports will be deleted).

The sensor keeps the AppEUi and DevAddr configured. However, LoRaWAN configurations (channel, data rate…) and applicative configurations are lost.

Factory reset
Way to trigger it	Two quick passages and a very long passage (until the sensor rings for the reset) of the magnet near the reed switch

Codecs are available to decode frames: Downloads

The SkyDome device implements “Analog Input” cluster associated to angle displacement measurement on EndPoint 0.

Skydome integrates the following clusters:

Cluster	Cluster name	Managed attributes
0x0000	Basic	All
0x0050	Configuration	All
0x8004	LoRaWAN	All
0x000C	AnalogInput (Vertical angle displacement)	All

Default configuration

A default configuration is set:

• The device reports each crossing of 27,5° angle displacement measured from position at sensor startup.

Every change made to the default configuration must comply with the legal duty cycle (for example, the most restrictive in the EU is 0.1%, which corresponds to approximately 1 frame per hour with SF12)

All frames have to be sent on port 125
