Sending information about the light intensity to the BMS

The above flow shows how to send information from the light sensor (dali2devs node) to the BMS via NodeRED. Change Node sets payload to payload.LUX. This means that it only transmits information about the illuminance level. This information is filtered by rbe node which will only send payload further if its different from previous, so if illuminance has changed this will pass payload further. After that it goes to BMS to revelant vertex by IP address and port number.

Group control 0-100 with BMS - when there is only one Vertex

This flow is for when we have only one node on site. First node (dali2devs) selects register number for group control and next switch node pushes forward payload for values less than or equal to 100. Next vertex action node sets brightness by direct value on selected group.

Feedback to BMS on the status of the group

Besides, we can transfer information about light illuminance, and we can also send general statuses to the BMS. To do that, we will need the vertex feedback node to get information from the device on-site and the function node to convert the JSON code into BMS information. As in the previous case, we will need the rbe node to send only this payload which is different from the previous one.

This example shows exactly the same as sending feedback on the status of the group but in this case we have multiple vertexes and we need to filter them somehow. To do that we can use vertex feedback node and select vertex IP address to which the device is connected.

When we have several vertexes on site and we want to have group control in range 0-100 with BMS. We should use Filter by Vertex node to insert IP address for vertexes devices groups we want to control.

We can control groups by scenes. To do that we need switch node to select one of the scene we want to activate. We have several vertexes in this case so we need to add Filter by Vertex node.

This example shows how our flow can give feedback to BMS about scene status with many vertexes on site. To select group from we want to get an information we should use vertex feedback node and then we can select vertex at Filter by Vertex node. Function node convert payload to select scene information from it and by switch node we can select scene we want to get feedback from. Next the change node changes name to keep our code clear.

Sometimes when an error occurs, it's good to have something to trigger a relay. To do that, we need to use the Modbus Read node, and then we can configure our Modbus server. It's important to remember that we should use only the first output of this node. From Modbus Read, the payload goes to a function node where it's converted into a message that will be understandable for the switch node, which decides if the error has been detected or not. Debug nodes are only for debugging.

There is a feature which we can use to change the sensor time from the BMS level. It’s useful when we have access to our system only through BMS.
