HI Benjamin, Thank you very much for your rapid answer. I tried with the device-id VScotHO1_200_01 but unfortunately got the same result (same error as on the screenshot above). For info my exact model is the Vitodens 200-W B2HB (35kw - Vitotronic HO2C) and the Vitogate is the latest model 7542150. I have a Mixer valve (7639040) connected to the KM bus to feed my floor heating system which is my only heating circuit. I also have a regular DHW tank (Vitocell 300-V EVIA-A), and a H1 extension on which a circulation pump for DHW is connected. Of course I also added a LON module and connected the terminating resistor on one side. My installation is configured with the parameter 00:04 and I can see the Vitogate on ID 98 when I use the "check LON subscribers", together with the "control ok" message. I also checked all these parameters in my Vitotronic according to the Vitogate documentation : 79:1, 77:1, 98:1, 9C:20 In ETS, I have assigned a device address to the Vitogate and did a full download of the application to push the address in. I have also connected the Vitogate via LAN, therefore I can successfully use it as an IP gateway in ETS (ie. downloading application into other KNX peripherals works fine). I tried to add the devices VScotHO1_200_01 (and previously VScotHO1_200_11) and only changed the parameter "Mixer" to "4. M2 + DHW". Then when I click the "Check devices control units" I always end up with the error shown above : "control unit is not present or present with a different system or subscriber number". I have also tried the automatic detection of my installation in the ETS plugin, but nothing is detected. Note that during these troubleshootings (trying to add different Device-ID, etc.), the LED light for LON status on the Vitogate which is normally "steady green" sometimes went to "blinking red" together with an error on the Vitotronic display about LON connexion. Removing the electrical plug of the Vitogate and plugging it again fixes that and the LON status becomes "steady green" again. It really looks like the Vitogate is unable to talk to the Vitotronic whatever I select. Note that I have the latest datapoint list (5.4.28) and product database (1.6). This is really annoying since the Vitogate is advertised as compatible with this regulation, and the fact that I cannot interact with my heating unit via KNX has quite a big impact on my home automation at the moment. I thank you very much in advance for looking into it. Best regards, Laurent
