It’s good to see that the WME (wood moisture equivalent) is now below 20% for all joists except one, indicated by the red line. This is the only sensor in the joist near where it enters the external-facing wall on the street side. I suspect what is happening is that the joist end is getting a bit damp from the brickwork in the wall – either from driven rain and/or rain splashing from the pavement, or from moisture bypassing the DPM from the crawl space wall.
– The elevated grey line is the sensor in the brick sleeper wall – not sure why it keeps going up and down.
– The bottom two lines are the two sensors inside the house
– The dark blue line (left hand side, third from bottom) is the external sensor
