Hello Smart Home Enthusiasts! 
I’ve been diving into the world of MQTT lately and I’m absolutely fascinated by its potential for home automation. I’ve come across some new attributes like state_class and last_reset that seem crucial for long-term statistics and energy monitoring. However, I’m curious if these attributes are fully supported in MQTT discovery yet. Any insights or workarounds would be greatly appreciated! 
Another project I’m working on involves automating roller blinds. I have a setup with 5 roller blinds in one room, divided into two groups. Each group has its own set of AC motors and I’m planning to connect them to Shelly2.5 devices for wireless control. While I believe this setup should work, I’m wondering if there’s a more efficient way to synchronize their operation, especially when using hard-wired UP/DOWN switches. Any wiring tips or alternative solutions would be fantastic! 
On a lighter note, I recently upgraded my OpenHAB setup to version 4.0 and it’s been a smooth transition so far. I managed to restore all my persistence data and graphs without any issues, which was a bit nerve-wracking. The Nashorn rules migration to ECMAScript was a breeze, and I’m relieved to see everything running seamlessly now. It’s amazing how the community continuously improves these platforms! 
If anyone has tips on optimizing MQTT configurations or innovative ways to handle multiple roller blinds, I’d love to hear them. Thanks for being such a supportive and knowledgeable community!
