I am not sure why this thread is in the UK forum since as far as I can see it seems to be discussing US only available options.
As far as I am aware and this appears to be still the case Yale have never offered Zigbee in the UK. They offer three modules -
- Z-Wave (now version 2 module which is Z-Wave Plus)
- Yale Home for linking to their UK alarm system
- A module specifically for use with their remote fob
They still don’t offer an Apple HomeKit module either.
Note: The US modules are a different shape to UK modules and in some cases will use different frequencies.
Yale’s UK support is now effectively non-existent even a US rep of Assa Abloy I managed to speak to via email admitted their UK support was bad. (And used this as an excuse why new products are not being released in the UK, i.e. support needs to be fixed first although if anything it is getting worse.)
Not only is the HomeKit support still not available in the UK but there is currently no sign of any August products becoming available either. (Assa Abloy bought August.)
