As for testing, we of course test these releases extensively before they go out. That said, it’s also important to remember that no two smart home setups are the same.
For example, I’ve personally been running this firmware since early May with around 26 connected Thread devices, next to that I’m also running 60 or so Zigbee devices. I haven’t experienced any issues.
So please reach out to support, that way we can see what’s going on.
The voltage the CPU is using is very different from the supply voltage of Homey as a whole.
A good analogy is a car engine. When you’re accelerating hard or driving uphill, the engine needs more power, so it uses more fuel. But when you’re cruising at a steady speed or idling, it only needs a fraction of that. Supplying the same amount of fuel all the time would just waste energy and generate unnecessary heat.
Modern CPUs work in much the same way. They dynamically adjust both their clock speed and core voltage based on the workload. When the CPU has little to do, it lowers both frequency and voltage to reduce power consumption and heat. As the workload increases, both scale back up automatically. This has no relation to the fixed supply voltage powering Homey itself or the Zigbee/Thread radio.
