Week 49, Day 4:

  • Mostly completing the commissioning of the intruder- and fire-alarm systems
    • Some issues getting the CSL DualCom GradeShift unit to connect to the monitoring centre (EMCS) using an analogue telephone line in parallel with the mobile phone network in order to ensure a reliable connection
    • The unit is connected to a Cisco/LinkSys Analogue Telephone Adapter (ATA) which in turn connects to a Voice-Over-IP (VOIP) service which was expected to present a good-enough analogue telephone interface but something isn’t working right
    • It’s not currently clear whether it’s a simple configuration issue or whether it really does need a “proper” analogue telephone line (in which case it might be best to swap over to an IP network connection for the alternative communication path)
  • More work on the lighting drivers, connecting up most of the remaining circuits
  • More work on the finishing touches on the inside – e.g. skirting boards in the Open Plan area

Week 49, Day 2:

  • More issues with the automated WordPress updates – I did a WordPress upgrade at the weekend and forgot to check whether wp-cli (which does most of the work for the automated daily updates) needed an update too (it did)
  • The final delivery of BPM light fittings from Phil at GreyBlue with some of them installed already – notably the two LUK CRUSADER which at 120mm in diameter seems enormous close-up but it’s a powerful fitting (30W of LED running at 900mA) and so only really suitable for large-scale installations
  • More work commissioning the internal and external wall-lights which are (mostly) simply switched rather than being on dimmer controls
    • These are controlled by a multi-channel KNX relay (not via DALI) and so need commissioning in KNX and some sort of user interface for control
    • After work I got a simple configuration working in OpenHab to be able to test these lights and they all work fine – I find it very pleasing to stand outside with a smartphone and turn the external floodlights on and off over WiFi
  • The main “nerve centre” in the Dressing Room on the First Floor is now nearly complete – just a few more switches to go
  • Off-site work by Mick machining the oak boxes for the staircase treads at the workshop
