How to merge Thread from HomeAssistant and HomeKit networks?

I discovered I have two Thread networks at house, instead of only one to expand coverage. How can I merge them?

In order for them to be the same network, they all need to have the same dataset (credentials). Apple doesn’t let you modify Thread datasets, but the other routers in your list should.

If you make MyHome your “preferred network,” you should then have an option in the OpenThread router’s 3-dot menu to “add to preferred network”. I’m not as familiar with ST, but you might be able to import the new dataset file like you did before.

That said, you should know that having lots of TBRs isn’t necessarily a good thing. A better way to expand your network’s reach is to use powered repeater nodes, similar to Zigbee or Z-wave, instead of adding more border routers which can complicate the network routing tables and have caused issues.
