Relay commissioning
- Joanna Kozakiewicz
- Jakub Grelak
If you have a single channel relay it will present itself as a single device, however if you have a multiple channel relay it will show itself as several devices.
The relay in the E2D UI looks like a luminaire as shown below (Device list → General lighting [1]):
Â
To control a relay device you should use the Set Brightness command [2] :
0% - relay is open, no power supply - OFF
>0% - relay is closed, the circuit is powered - ON
To manually control the relay you can use this Power switch to turn it ON and OFF.
How to commission it?
The getting started with Node-RED section is here: Programing logic (Node-Red)
This example shows how to use a relay to control ON-OFF luminaires using a time scheduler. The DALI relay will turn the light on every day at 8 a.m. and turn it off at 6 p.m.
Import the ready made flow using the instructions here: Importing a Node-RED flow or follow the instructions below.

Find the following nodes:
|
Create an inject node for scheduling the OFF commands. Set the node payload as 0 and the node topic as OFF [3] and in the repeat section choose the day and time when the lights will switch off [4]. To end configure node click Done at the upper corner of the window [5].
Create an inject node for scheduling the ON commands. Set the second node payload as 1 and the node topic as OFF [6] and in the repeat section choose the day and time when the lights will switch on[7]. To end configure node click Done at the upper corner of the window [8].
Create a Vertex action node for the off commands [9]. Select single button mode[10]. Choose the action: set brighness, the group that is to be controled and 0 for the brightness level[11].
Create a Vertex action node for the on commands[12]. Select single button mode[13]. Choose the action: set brighness, the group that is to be controled and the brightness level (any value more than 0)[14].
Connect the nodes together as shown above and connect them to the cluster node (create one if needed).
Do not forget to click Done and Deploy!
