St Columba’s by the Castle

On St Andrews Day (30 November 3015), we set up our equipment in St Columba’s by the Castle for the first beta-test – can we get a range of equipment all to report from the same site at the same time?

Some essential data:

  • some gas meter readings (I believe Iain has more):
  •                   030070.00 cubic feet (30 Nov 15, 11:44)
  •                   030602.60 (11 Feb 16, 09:50)
  •                   030639.40       (16 Feb 16, 09:37)
  •                   030644.40  (16 Feb 16, 13:07)
  •                   030680      (18 Feb 16, 16:36)
  • electric meter readings – I hope enough to sanity check our monitoring:
  •                   65386 kWh (30 Nov 15, 11:47)
  •                    69175 kWh (18 Feb 16, 16:36)
  • Humidity readings at start:  (node 2) 56%, (5) 56, (9) 54, (10) 55, (14) 55, (CMM80) 69%.  We probably didn’t leave things long enough to settle – we’ll come back to this question of calibration as we go along.

Here are the live graphs.  You can find out more about what’s on site, and what we plan to do with it – in our blog post.  Because of the radio distances,  there are more missed readings than usual – straight lines skip over these.  As always, if you can’t see anything, mouse over the graph and try pressing D for day or M, for month. If you still can’t see anything, our equipment has been down for a month (!) and you may need to tweet us. You can mouse areas of the graph to see more detail.

Boiler Flow Temperature (Hall)

This sensor was attached to the boiler flow (look back to before 22 Feb 16) – a pipe coming out of the boiler, feeding hot water to the radiators in the hall.  It’s probably only useful to tell us when the heating comes on, and what kind of readings we get on bare pipe for a boiler set to 80C! Until 2 Dec, our software accidentally filtered out all readings above 50C.  The radio was on the edge of range – so we are getting long periods of down-time.  As we see it, this situation will provide the perfect test for radio tweaks, once we make them.
