As a homeowner exploring the integration of various smart devices, I recently encountered an intriguing challenge with my RFXtrx switches. While configuring my bedroom lights, I noticed that two wall switches with the same home/unit code were conflicting, causing one to be ignored by Home Assistant. This was puzzling, as both switches were from different brands and should operate independently.After some research, I discovered that the issue stemmed from the way the RFXtrx platform processes device IDs. It appears that only a specific portion of the ID is used as the primary key, leading to conflicts when the home/unit codes overlap. To resolve this, I adjusted the home/unit code of one of the switches, which immediately resolved the conflict and allowed both devices to function seamlessly.This experience highlighted the importance of thoroughly understanding device configurations and the nuances of different smart home platforms. It also underscored the value of community forums, where users like Dennis have shared their insights and troubleshooting steps, making it easier for others to navigate similar challenges.For anyone else dealing with RFXtrx or similar devices, I recommend carefully reviewing your device configurations and considering adjusting codes to avoid conflicts. It’s a small tweak that can make a big difference in maintaining a smooth smart home setup.
