Connect HA to wago

[mykel (Mickael)]

Hello Everyone,

I’m new using HomeAssistant and I would like to switch my old Calaos system to HA.
Thanks to a crash of my Calaos configuration / server, I can’t restore the settings and, unfortunately, I’m blind and need to configure everything from scratch…
I’m not an expert into coding, and my skills are limitated

What I have is a Raspberry with HA installed. I can use the calaos Installer tool to communicate with the Wago and, thanks to WireShark, I can catch the packets sent to the wago. So my need here is to mimic the instructions sent to the wago with HA.

For example, turning on the light of my kitchen with CalaosInstaller leads to:

62 bytes on wire (496 bits), 62 bytes captured (496 bits) on interface \Device\NPF_{1F298A48-F9CD-4C7C-BE8A-0B645AEC7340}, id 0
Ethernet II, Src: Intel_de:d0:14 (5c:87:9c:de:d0:14), Dst: WAGOKontaktt_03:ac:f5 (00:30:de:03:ac:f5)
Internet Protocol Version 4, Src: 192.168.1.24, Dst: 192.168.1.123
User Datagram Protocol, Src Port: 4646, Dst Port: 4646
Source Port: 4646
Destination Port: 4646
Length: 28
Checksum: 0x8411 [unverified]
[Checksum Status: Unverified]
[Stream index: 0]
[Timestamps]
UDP payload (20 bytes)
Data (20 bytes)
Data: 5741474f5f5345545f4f55545055542032352031
[Length: 20]

The data means something like WAGO_SET_OUTPUT 25 1 (Wireshark interpretation).

Does anyone know how to proceed? I heard about modbus but I don’t know how to use it…

Any help will be very helpful.

Thanks a lot

If you need to send UDP to it, this topic might help:

WTH isn’t UDP comms integrated in HA?

UDP is an essential comms protocol used by many devices. On my computers I run a python script that listens and sends on certain UDP ports. As I know it’s easy to include UDP binding and sending in Python I wonder why it isn’t part of the HA integration. Now I have to send my commands to netcat via a service call to shell command. Which works, sort of. When you have no variables in your string. Or else the shell command breaks when it reaches the pipe symbol. I’ve been trouble shooting this a…

Hi Mickael, welcome to the forum!

FYI I don’t know if this can help: there is a custom integration to get Calaos inputs and outputs states, as well as trigger Calaos outputs.
