Very likely not going to happen. The temperature/humidity sensor were already discovered at the teardowns of the homepod on release. But there's no indication of an ant+ chip in apple watches. It could theoretically be hidden in the SoC but as ant+ is a proprietary technology by the watches biggest competitor, garmin, it won't happen.All I want is health/activity on iPad.
Then watchOS workout app to support ant+ sensors for biking.
I know I know.. The watch doesn’t even have an ant+ capability. But there is still a small glimmer of hope that it does and just hasn’t been enabled similar to the HomePod temperature sensor.
