Basic information
teleRelays-2D device is a type of smart relay that provides the possibility of
control via LoRa interface. Unlike conventional relays, which have only the
basic switching functions for which they are intended, this type of device has
built-in microcontroller that allows it to be integrated into smart control
systems, thus offering the possibility of use in different systems (e.g.
heating system control, cooling system control, lighting management and other
systems).
The basic version of the device contains the following connectors:
- two-pin connector for device power supply with a voltage of 220 VAC
- operating contact for switching functions (ON/OFF)
In addition to the connector, the device also includes the following components:
- switch for turning ON/OFF device
- power indicator (red LED light)
The device communicates with other devices via the LoRa interface using the
permitted unlicensed frequency spectrum specific to the region in which the
device is located (Europe 868 MHz, USA 915 MHz, etc.). The device receives
certain set of commands from several types of devices through the indicated
interface and, if necessary, returns responses to these devices.
WORK PRINCIPLE OF DEVICE
teleRelays-2D has two-way communication with the devices with which it is
paired. The device continuously listens to any message that arrives via the
LoRa interface, and in case of receiving data, the device checks the message
and if it determines that the message is not intended for it or is a message
from a device with which it is not paired, the data will not be processed
(except in cases where an unpaired device sends a pairing request). If the
message intended for the device came from the device with which tele Relay is
paired, then the message is processed. In other words, it cannot happenn that
the device responds to a command or message from another device with which it
is not paired.
The set of commands that the device can receive is diverse. The device can
receive request for registration/deregistration, to turn ON a certain relay/s,
to turn OFF a certain relay/s, to turn ON/OFF all relays at the same time,
etc.
The reposnse of the device to received and processed commands is minimal and
is equal to the latency of radio transmission (several tens of ms), which the
user cannot even notice in reality.
Registration/deregistration mode
As already stated, the device can receive registration/deregistration requests from certain devices from the group that is allowed to register to teleRelay devices. The device keeps data about registered devices in its memory, and if a new registration request arrives, the device will write a new record with data about that device into the memory (a maximum of 20 devices are allowed to be registered to teleRelay devices). Likewise, if the device receives a request for deregistration, the data about the device, if it was previously registered, will be deleted from the memory.
The device is in the registration/deregistration mode 30 seconds after the initial power-on, after this time the device ignores all requests for registration/deregistration, and it is necessary to turn the device OFF and ON again in order for the device to enter the registration/deregistration mode.
Indicator that device received registration/deregistration is the switching ON and OFF relay output 1, and is explained below:
- a single ON/OFF of the output is an indicator of successful registration request receive
- a double ON/OFF of the output is an indicator of successful deregistration request receive
Normal working mode
As already mentioned, the device continuously listens for new commands and
acts in accordance with them. Given the nature of LoRa communication, the
device receives all types of messages from devices in its range, but only
those messages that are from valid group of devices are processed further,
while all other messages are ignored. If the message passes the check of the
allowed group of devices, it is further checked whether that device is
registered in the memory of the teleRelay device, if not, the message is
ignored, if the device is registered in the memory of the teleRelay device, in
that case teleRelay executes the command contained in the message.
The device can receive a diverse set of commands, which can be: turning ON/OFF
a specific output or group of outputs, inverting the current state of an
output or group of outputs, turning ON/OFF all outputs on the device, etc.
DEVICE WIRING INSTRUCTIONS
Device Power Supply
The two-pin connector labelled with N and L is used to power the device.
Relay Wiring
The relay working contacts are connected in series with the circuit we want to control. It is necessary to connect the circuit to connectors 1 and 2, as shown in Figure 4.
