I recently installed openHAB and configured it using the openHABian setup guide, which worked smoothly. However, I encountered an issue where Homegear couldn’t connect to my HM-MOD-RPI-PCB. The logs showed repeated errors stating ‘No init packet received,’ which was perplexing. After some research and trial and error, I found that the problem was related to the GPIO configuration on my Raspberry Pi. I adjusted the settings to ensure the correct pins were being used for communication, and the issue was resolved. This experience taught me the importance of checking hardware configurations when dealing with connectivity problems. If anyone else is facing similar issues, I recommend verifying your GPIO settings and ensuring that the firmware is up to date. Happy troubleshooting!
