Sadly, it seems to be Bluetooth only, whose range isn't great unless you already have your garden covered. Probably late to ask, but would be cool if future versions also included a Zigbee radio and it will make it 1000 times easier to integrate into Home Assistant :)

Yes— this version is Bluetooth only, which works well for many smaller setups but does have its range limitations. I’ll pass your suggestion for Zigbee radio along to our product team! Expanding connectivity options is something we’re actively exploring for future versions of this Monty.

For larger-scale setups, our upcoming industrial product line, Monty Pro, will feature LoRaWAN connectivity, offering a much wider range. You can learn more about it here (https://www.monty-pro.com). While it’s designed for industrial composting, if there’s interest in hacking it for personal setups— we’d be open to making this available to the community!
