Hello everyone, I hope this message finds you well. I recently encountered an issue with sending emails through Gmail SMTP in OH2, and I wanted to share my experience and solution in case others are facing similar challenges.
The Problem: I was trying to set up email notifications in my OpenHAB setup but kept running into errors. The error messages indicated a connection timeout to the SMTP server, which was puzzling because I had used the same settings successfully in OH1.
The Investigation: I started by double-checking my settings. The hostname was correctly set to smtp.gmail.com, port 587, and I had the correct username and password. I also ensured that TLS was enabled. Despite all this, the issue persisted.
The Solution: After some research, I realized that the issue might be related to JavaMail, which OH2 uses for email functionality. I found that updating the JavaMail library to a newer version resolved the problem. Additionally, I made sure that my firewall wasn’t blocking the connection and that I had allowed less secure apps to access my Gmail account, which is sometimes required for SMTP to work.
Tips for Others:
- Always verify your firewall settings when dealing with connection issues.
- Check if there are updates available for your email binding or JavaMail library.
- Ensure that your email provider allows less secure apps if you’re using a standard SMTP setup.
Conclusion: It was a bit frustrating at first, but breaking down the problem step by step helped me identify the root cause. I’m glad I could resolve it and now have reliable email notifications in my smart home setup. If anyone else is struggling with similar issues, feel free to reach out, and I’d be happy to help!
Happy automating!
