Called my (soon to be former) HVAC vendor[1] and the call was answered by an AI human voice… that did not disclose it was an AI.

It pretended to be human. After 2-3 exchanges (as awkward as you'd expect), I asked.

I'm not sure I've ever been more ready to run away from a vendor. I escalated to a real person, who was thrilled to pass along my feedback.

Швейцарский нож Инженера АСУ ТП: Ищем, подслушиваем, настраиваем и шьём по Modbus одной утилитой

При проведении пуско-наладочных работ на объекте Инженерам часто приходится иметь дело с "солянкой" различного оборудования на линиях RS-485, передающих данные по Modbus RTU на "средний", или "верхний" (в BMS\SCADA) уровни. Написали программу, которая умеет искать Modbus RTU устройства по COM-порту, а так же через преобразователи интерфейсов с протоколами Modbus RTU over TCP и Modbus TCP. Прописали IP адрес и порт шлюза, выбрали протокол и готово.

↙️I'm glad that #MIT startup #transaera found a secret sauce for HVAC dehumidification: coupling a new solid desiccant with heat pumps!

↘️I worked on reducing solid and liquid desiccant #HVAC costs back in the 1990s; see "Reduced-Cost, Desiccant-Based DHC Systems"
