House 3 on the day

House 3 holds three benches of tomato seedlings under a gabled glass roof. The inspection checks that the roof vents, the heater and the two climate sensors keep the house between 16 and 27 degrees Celsius.

Sensor A sits above the middle bench and sensor B near the door. Readings for the week are on page 2; actions are on page 3.

The full sensor log is attached to this PDF as a CSV file, and the technician's notes are pinned to page 3.

The house went over the 27 °C limit on two days, Wednesday and Friday. On both days the vents opened later than the controller schedule says.


Actions and sign-off

Actions

1. Move sensor B away from the door, where drafts lower its readings.

2. Reset the vent controller to open at 24 °C instead of 26 °C.

3. Service the heater before the first frost and record the date here.
