Hey everyone! 
I’ve been working on a Home Assistant integration for Elektrobock EOB WiFi devices and thought I’d share it with the community.
What is this?
It’s a custom integration that lets you control your TS11 WiFi Therm Smart Outlet directly from Home Assistant. You get full climate control, temperature monitoring, and relay management through MQTT.
What can you do with it?
Set target temperature and see current temperature in real-time
Switch between AUTO, HEAT, and OFF modes
View and adjust attenuation and comfortable temperature settings
See your weekly heating programs (read-only for now)
Control the relay — turn heating on/off
Also works with TS11 Socket (on/off control)
How to install?
Super simple:
- Add to HACS: GitHub - jakubhegr18-design/eob-wifi-hass: Home Assistant custom integration for Elektrobock EOB WiFi devices (thermostats, relays, sensors) · GitHub
- Search for “EOB WiFi” in HACS
- Install it
- Add integration with your EOB WiFi app login
That’s it! Your devices should show up automatically.
Current status
TS11 Therm — is being worked on
TS11 Socket — partial support / Not Known
PT14 and U2 — not yet supported / Known
The integration talks to Elektrobock’s cloud API and MQTT server, so you don’t need to mess with your local network setup.
Known limitations
- Writing some settings (like attenuation temp) requires capturing the actual API calls from the mobile app
- Weekly program editing not yet implemented
- Still in beta, so there might be bugs
Help Wanted! 
If you manage to get this working with the Normal TS11 PT14 U2 or discover new API endpoints for writing settings — please share! Either open an issue on GitHub or reply here. Your findings will help expand support for more devices. Every bit helps! 
If you try it out, let me know how it goes! Any issues or feature requests — just post them on GitHub.
Thanks!
