I’ve been diving into optimizing my Vera 2 system lately, and I thought I’d share some insights and questions I’ve come across. If you’re like me and have a decent number of devices (70+), you might be familiar with the occasional slowdowns. I stumbled upon a post suggesting creating a swap file on a USB drive to help with memory management, which sounds promising but has some unanswered questions.
First, the process involves creating a swap file using dd and mkswap, then enabling it with swapon. The concern is whether this swap file persists after a reboot. Would adding the swapon command to Vera’s startup be feasible? And more importantly, are there any risks associated with using a swap file in this context?
Another angle I’m exploring is whether I’m hitting the practical limits of Vera 2 with so many devices. I’m currently on UI5 with all updates applied, but the memory usage is quite tight. The FREE command shows minimal free memory, which could be a bottleneck.
On a different note, I’ve also been experimenting with temperature monitoring using DS18B20 sensors. Setting up alerts for temperature thresholds was a bit tricky, especially with decimal precision. It took some trial and error, but I finally got a rule to trigger notifications when the temperature drops below 5°C or rises above 7°C. Sharing these kinds of solutions is what makes this community so valuable!
If anyone has tips on optimizing Vera 2 for a large number of devices or insights into using swap files safely, I’d love to hear them. Let’s keep the conversation going and help each other tweak our setups for better performance. Cheers!
