TechniSat Digit ISIO S2 Controller

Node.js/Express HTTP API that controls the TechniSat Digit ISIO S2 via its UDP port 8090 protocol (TechniSat Connect / ConexusTS protocol). Channel switching and remote control button presses are delegated to a Python script.

Protocol

The receiver accepts XML packets over UDP port 8090. Example:

<rcuButtonRequest code="1" state="pressed"/>
<rcuButtonRequest code="1" state="released"/>

Channel switching works by sending digit key presses followed by OK — the same as using the physical remote.

Setup

npm install

Python 3 is required for technisat.py (no extra packages needed — uses stdlib only).

Running

# With a fixed device IP
TECHNISAT_IP=192.168.1.100 node server.js

# On a custom port
PORT=8080 TECHNISAT_IP=192.168.1.100 node server.js

API

All endpoints accept an optional ?ip=<device_ip> query parameter to override the default TECHNISAT_IP.

Method	Path	Description
GET	/	List endpoints
GET	/channel/:number	Switch to channel
POST	/channel	Switch to channel ({ "channel": 3 })
GET	/key/:name	Send a key press
GET	/discover	Broadcast device discovery
GET	/info	Request device information
GET	/keepalive	Send keep-alive
POST	/text	Send text input ({ "text": "hello", "enter": true })

Examples

# Switch to channel 3
curl http://localhost:3000/channel/3

# Press the RED button
curl http://localhost:3000/key/RED

# Switch channel with explicit IP
curl "http://localhost:3000/channel/7?ip=192.168.1.100"

# Volume up
curl http://localhost:3000/key/VOLUP

Python script (standalone)

# Switch to channel 5
python3 technisat.py 192.168.1.100 channel 5

# Press the OK button
python3 technisat.py 192.168.1.100 key OK

# Discover devices on the network
python3 technisat.py 255.255.255.255 discover

# Get device info
python3 technisat.py 192.168.1.100 info

Proxmox deployment

Run on any LXC/VM that can reach the receiver's network. The server binds to 0.0.0.0 so it's reachable from other VMs or the host.
