 ==Status==
+====Debugging====
+* I added a fair bit of code to log the various states of the system to try and determine why it over counts.
+* Writing to the serial port takes time I had to place the logging code carefully so as not to interfere with the critical timing of beam break detection.
+* I now have a log file to analyse which includes a good amount of traffic from a Tuesday evening.
+* Summary stats from the log file:
+:Beam breaks:
+;Outer:     655
+;Inner:     694
+:Actions initiated:
+;Entrances: 401
+;Exits:     337
+:Actions completed:
+;Entrances: 173
+;Exits:     129
+:Actions never completed - timed out - noise:
+;Entrances: 84
+;Exits:     83
+:Actions not counted because they were fast/slow:
+;Entrances: 144
+;Exits:     125

 * Beams are now polarized
 * Beams are now very close together
-* Temporary prism reflector being used (permanent replacement on order)
+* Prism reflector
-====What next====
-* Fit reflector
-* Move sensor closer to door
-* Try some different timing configurations to improve detection
-* The [https://github.com/londonhackspace/spacensus python script] that provides the data to cacti implements only the 'poll for status' command, but will later allow more control and configuration of the counting sensors.
