For my own reference:
- It looks like the Nest needs to communicate wirelessly with the Heatlink in order to support OpenTherm. I can’t find what frequency or protocol the Nest/Heatlink connection uses.

- Nest Introduces Nest Weave, Creating Most Comprehensive Developer Platform for the Home | Nest
- Nest devices interconnect with each other using a protocol called Weave, which is based on IEEE 802.15.4 and Wi-Fi 802.11 b/g/n.[30] which seems to indicate it operates mostly on 2.4Ghz (which is distorted when neighbours use their Microwave to heat food).
