🔧 Grok 4.7 is coming — and #HVAC businesses might win biggest.
Musk says it’ll crush real-world engineering thanks to SpaceX training data. Better diagnostics, smarter maintenance, faster tech training… the trades could get a serious edge.

It is appalling that PLC devices are connected to the Internet. I get why it happens, a former company I worked for had a vendor install an SCADA + HVAC system, networking provided a standard drop without configuring the specific restricted VLAN. That system was open to the internet with the default password as "password." No one checked the network other than active connectivity and the system was put on the internet.
For water and power companies it is unbelievably negligent to connect SCADA to the Internet. There should be no reason why we need task force, after task force to solve this entirely self owned problem. This was a problem back in the early 2000s and systems are still placed on the Internet.
What is a solution? How about a private network between utility companies with encrypted traffic, not connected to the open Internet. If Internet monitoring is required, configure a very secure VPN to a DMZ.

if i switch the air conditioning unit to dehumidify (its located near the kitchen atm), would that help remove strong cooking smells?

Questions for people who control their environmental temperatures with heat pumps (and only people with first-hand experience):
1. What is the optimal operating temperature range for your heat pump? (I.e., lowest temp it operates in efficiently for heating, highest temp for cooling)
2. When you can't use it because temperatures are outside that range, what do you use a back-up heating and cooling alternatives?

I keep reading about Corsi–Rosenthal boxes as DIY air purifiers that outperform all commercially available air purifiers.
You literally only duct-tape four HVAC filters together and slap any regular PC fan onto them.
US-Americans recommend the brand #Filtrete for MERV-rated HVAC filters, but in Europe that brand costs at least twice or thrice as much as in the USA.
Are there any equivalent affordable HVAC filters in Europe with a MERV rating of 8 or 13? Or do I simply have to swallow the additional cost because HVAC filters aren't as ubiquitous in Europe as they are in North America?

HVAC filter System

This system will cost you between 30 and 60 US dollars replacing 300 US dollar systems

In the Canadian Smokestream right now! Graph from #HomeAssistant, showing PM2.5 readings. Outside is from the nearest station reporting to #WAQI, inside from #IKEA Vindstyrka. At 8pm, I switched from washable HVAC filters to MERV10 disposables. Around midnight, turned on #CorsiRosenthalBox, full speed. (Same room as sensor.)
So, #hvac was doing ok, MERV10 improved it. The CR really made a big difference, and quickly, lowering the level about 2.5x. -

Хотел написать регулятор для руфтопа. Пришлось решать дифференциальные уравнения
В прошлый раз я писал про голосового ИИ на Asterisk и Яндексе. Фурора не случилось, но статью открыли семьсот с лишним человек, в ленте её увидели тысячи, а в комментариях нашлись те, кто делает ровно то же — с той же болью и теми же вопросами про задержки и оценку качества ответов. Значит, тема живая, и про свои проекты писать имеет смысл. Сегодня — про другое, с виду куда более скучное: регулятор для руфтопа. Руфтоп — это крышный кондиционер, большой ящик на крыше торгового центра. Логика — по сути термостат с амбициями: держи температуру, включай компрессоры по запросу, не дай им зачастить. Я закладывал пару недель. Кончилось это системой дифференциальных уравнений с собственным движком, которая пять раз убедила меня, что всё работает, а потом оказывалось — неправильно. А главное — кончилось не регулятором вовсе. Регулятор оказался тривиальным. Настоящая работа была в другом: научить систему честно говорить, что с железом не так, — и не соврать при этом ни одной цифрой. Голый тезис на весь текст: термостат — это просто, пока не спросишь, что физически происходит внутри. После этого вопроса начинается наука. А приборы, которые показывают «всё в норме», врут убедительнее всего — и заставить их не врать труднее, чем написать сам регулятор. Читать и пить кофе

Does anyone in the Portland, Oregon area happen to need a few 14x24x1 furnace filters? Our new setup takes a different size and it seems a shame for them to go to waste.

3 days during Maryland heat dome event. HVAC used 41kWh + 15kWh, so 56kWh with heat pumps keeping the house at 75f. My personal data center used 78kWh 😆 But it was all solar powered....and my neighbors too! #solar #heatdome #renewables #hvac #airconditioning #energy

Having an #HVAC discussion and I wonder if a misconception about modern "mini-split" #heatpumps is that you're limited to having that thing on the wall in each room. You aren't. Our house was built in 1934 and the rooms are all small - this wasn't open-plan living - so that meant multiple heads and that was ugly and expensive. So, instead, we have a unit that sits in the basement where the furnace used to be and uses the existing ductwork. And our upstairs unit is mounted in the ceiling.

@voiceofunreason @yantor3d yeah we didn't have anything until we replaced the oil heat and tank with our Mitsubishi Mr Slim, but that was also paired with insulating the house and solar panels, so it was an enormous project. My career advice for young people is #HVAC because the majority of houses in #Portland probably need the same thing and no AI is going to do it.

Well crap. #HVAC is busted. AGAIN. It's been off for months and now it's suddenly randomly turning on the blower motor and turning it off. When it turns on it will stay on for hours. Completely disconnected thermostat and it still does it. Has my ECM blower motor crapped out for a THIRD time? #HomeRepair #DIY

apparently the company/product that lost me as an HVAC customer is called Avoca: https://www.avoca.ai/customers/apex-service-partners

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.
1: BelRed Heating/Gene Johnson, which is one of many trade names of Apex Service Partners. fuck them.

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.
