On Saturday we had scattered showers, no make that storm clouds, (occasional heavy hail) with the odd patch of blue sky. The hygrometer in the bathroom confirmed the solarventi panel had been in action. When I returned from my travels over lunch, the relative humidity still registered 40%, and temp was 21.7 degrees C. even though the sun was not out that much.
The house "norm" is 55-60% and our central heating is set at 20 degrees.

OK, so my hygrometer has fallen from it's mounting, as you can see to the right, it now rests on the wall cabinet (far right, behind the Johnson's baby shampoo bottle). The readings are none the less encouraging. Sunday was dry and bright. The images were taken that afternoon.
As I stood peering at the hygrometer, my breath caused the humidity reading to rise from 23 to 27 in seconds. Humans are a major cause of damp in houses too. Just breathing adds moisture to the atmosphere.
The two temperature readings are internal 27.9, and external 18.4. The wire runs outside to a sensor on the wall behind the solarventi panel. The general outside temp was 10 degrees at the time, or so the car instrumentation said as we drove home from church. So the external temp is boosted by being in proximity to the panel.
