I’d like to integrate the Relay LAN Board DS2824 from Robot Electronics into OpenHAB 3.
It has 24 relays (capable for 230V / max. 16A) that can be managed via LAN.
There seem to be four possible modes to manage the board:
- TCP / IP command set (like: “IP Port SR 1 on” to set the first relay on or “IP Port GR 1” to get the status of the first relay)
- Binary command set (setting the comands by bytes like 0x30)
- AES binary command set (like 2., but including encryption)
- modbus commands.
I suppose it would be the most easy for beginners to use the TCP / IP commands with the http-bindings, but I still find no tutorial where and how to put the commands in the binding configuration.
Can somebody pls give some hints?
Thank you very much!
PS: You might find the documentation about the mentioned board here in a zip-file: dScript software
TCP / IP commands are not compatible with http binding.
You would have to use the TCP/UDP binding.
But as mdobus is supported I would assume that that one is more straight forward.
Thank you very much James - I think I will inform me (in future) about Modbus TCP and trying to get it work starting from your hint… the problem is: I have not much idea about Modbus and few time to get it work, so this must wait a little (although it might be the much better or solid way).
Thank you, too, Wolfgang: I looked for an TCP/UDP binding, but still did not find any in the list of my installation…
Under settings go to “JSON third party addons” ( could be named a bit different as I do not have english as UI language ). There you need to enter
This will add smarthomej to the marketplace. Afterwards you should be able to find "SmartHome/J TCP/UDP Binding "
Hi Wolfgang, I found it - thank you very much! Markus
