5. DATA PROTOCOL
If you are using your own server, you need to know data protocol, i.e. data packages and
communication flow. First of all, it is necessary to create an application on the server and
add the device using the appropriate keys. If the server application is created and the device
is added to it, then the device can be turned on and the JOIN procedure can be started. Once
the device is successfully JOINED to the server, it can start sending and receiving messages
to/from the server.
5.1. teleRelays-2L Data Packages
The data package that teleRelays-2L sends to the server has the following format:
<relay_states>
relay_states is 1 byte data and represents the current state of all relays on the device.

Table 1. Reference for creating a relay state data formatters
Each bit in the relay_states data represents the state of an individual relay, as shown in
Table 2. If the relay is active, its state is marked with 1. Otherwise, the state of the relay
is 0.

Table 2. Bit values in relays_states data
The data package that the server sends to the teleRelays-2L device can have one of the
following formats depending on the selected mode:
1. If ON, OFF or TOGGLE mode is selected, the data packet has the following format:
<command >< relay_number><timer_value>
2. If DELAY ON or DELAY OFF mode is selected, the data packet has the following
