Here is the order I would do things to minimize false rain:
- Unplug the hub.
- Take the Tempest off its mount and turn it off. This will make sure that it forgets the false rain it recorded while removing it from the mount.
- Get the new mount all setup and ready for the Tempest.
- Just before you put the Tempest on the mount turn the power on and quickly mount it. It will take a moment to boot up and if you are quick you can be done before it begins to record again.
- Go plug the hub back in.
- Verify that the Tempest is sending data to the hub and the station is working. Remember it takes a bit for the hub to boot up so don’t panic that the light on the hub doesn’t come on immediately when power is applied.
Hopefully that pipe is 1" pipe size and not exactly 1" as it will be too small for the pole mount. Also, realize that wind will be effected at that close to the roof.
