Hello Rich, welcome back to our community.
These gaps paired with the roof work you have described are an interesting coincidence indeed.
Two things:
-
Are the gaps appearing also in the helicorder files created by the Shake itself? Could you access
rs.local/
and click on theHelicorder
icon in the lower left. Once in theRecent Helicorder Displays
page, could you select the one(s) that matche(s) the day and time of the roof work and post them here? -
Could you please download the logs from the Shake and post them too? If you require, instructions on how to do so are on this page: Please read before posting!
Thank you.
