Hello everyone! I’ve finished my work on the PR that adds SDM support to the Nest Binding and marked it as ready for review. 
If you want to help with testing/reviewing, here are some links to JARs:
- org.openhab.binding.nest-2.5.13.20210530.jar (retro OH versions: 2.5.0, 2.5.1, … 2.5.10, 2.5.11, 2.5.12)
- org.openhab.binding.nest-3.0.3.20210530.jar (older OH versions: 3.0.0, 3.0.1, 3.0.2, 3.1.0.M1, 3.1.0.M2, 3.1.0.M3, 3.1.0.M4)
- org.openhab.binding.nest-3.1.0.20210530.jar (newer OH versions: 3.1.0-SNAPSHOT, 3.1.0.M5)
There’s also an updated README.md which documents how everything should be configured.
