Hi Tomasz,  
I’m having an issue with the app and I’ve submitted a diagnostics report — ID: 65e2826c-3aba-4573-9ee2-c357515ba6cd  
Setup: Zehnder ComfoAir Q650 with ComfoConnect LAN C gateway, app v1.5.5, Homey Pro.  
Problem: the device pairs successfully, but all capabilities remain null — no temperatures, humidities, airflows, bypass state, fan speeds, filter days. Nothing ever populates.  
Control appears to work but doesn’t. Setting fan\_speed\_mode returns success and the value updates in Homey (I tried 1, 2 and 3), but the unit itself stays on speed 2. I verified this two ways: on the unit’s own panel, and via a metering socket the unit is plugged into — power draw stayed at 89.9 W across all three settings, unchanged. So the commands never reach the gateway.  
What I’ve already tried:  
• Re-paired the device twice (it now appears as “ComfoConnect LAN C”)  
• Removed the second unit I had paired, so only one remains  
• Verified the gateway IP on my switch (link is up, uptime over a day)  
• Restarted the app after changing IP/PIN, as the README instructs  
• Tried the installer PIN instead of the default 0000  
None of it changed anything. No error is ever shown — earlier I got “device unavailable” and 10s timeouts, but after re-pairing the commands just silently succeed and do nothing.  
Happy to run any further tests or submit another diagnostics report if that helps.  
Thanks for your work on the app!
