i have no problems with all that. I just dont like my laptop sitting on top of an 8 ft ladder while doing it. Another company installed the controls in the building and reused the comm wires from whatever system predated it. The whole building is a mess due to a lazy install. Wrong wire, not wired in proper daisy chain, multiple splices, list go on and on. Currently we are trying to work with customer to keep it running until a long term fix can be budgeted.
