Do protocols based on the publish-subscribe pattern negate the benefits of mesh networks?
Protocols that are modelled on the publish-subscribe pattern such as MQTT and AMQP require a centralised message broker to co-ordinate messages being sent and received. This does not pose much of a problem when your IoT network is based on a star…

Range of BLE and IEEE 802.15.4
In theory, IEEE 802.15.4 (ZigBee, Thread etc.) can achieve a much larger range than Bluetooth Low Energy (conventional, not coded PHY) due to its usually higher sensitivity (see for example here or here).
I have noticed the same in my own…

Could a zigbee device be updated via software to support thread?
It's known that zigbee and thread use the same physical layer, just the application layer is different. Given that, is it theoretically possible to do a software/firmware update to a zigbee device and make it thread?

Matter (like Thread) support in Australia - almost zero. Would a zigbee Smart Home be compatible?
I'm just starting my smart home journey and have been investigating. I prefer open and no vendor lock-in solutions and think Matter will be the solution for me, with Thread being a protocol heavily discussed wrt to it.
What is Matter
