Oh, this is just a masterpiece of investigative work. Truly. I haven't seen this level of inspired, reckless curiosity since I watched a junior developer discover you could query the production database with SELECT * without a LIMIT clause. You've peeled back the onion on your HVAC system and, to absolutely no one's surprise, found a rotten, insecure core.

It's truly admirable how you identified a critical flaw in the manufacturer's support process—namely, that their entire authentication model is based on the honor system. You didn't just find a workaround; you performed a successful social engineering penetration test and then, in a stroke of genius, published the exploit and the target's direct line. Chef's kiss. Why bother with phishing emails when you can just tell people to lie? It's a bold strategy for brute-forcing the human firewall, I'll give you that. I'm sure Durastar's legal and compliance teams are thrilled to see their trade secrets being handed out by a support engineer to a man who successfully spoofed his identity as "some guy from Indiana."

And the "feature" you uncovered! Oh, it's just beautiful. It’s not an undocumented feature, my friend; it's a pre-installed CVE. You're celebrating that your climate control system, a critical piece of infrastructure for your home, operates on a stateful inference engine with an unauthenticated, non-standard input vector.

...learn the set point by tracking the 24V thermostat’s calls for heating over time.

So, let me get this straight. The system's core logic is based on guessing. It's a black box algorithm that's trying to predict user intent based on a noisy, binary signal. What could possibly go wrong? You think you're getting "smoothing," but what you've found is a perfect vector for a denial-of-service attack. A malicious actor with access to your "smart" thermostat—which, let's be honest, is probably an IoT device with the security posture of a wet paper bag—could just send a few irregular pulses on that 24V line.

• Congratulations, you've just confused the inference engine. Does it ramp to 100% and burn out the compressor?
• Does it shut down entirely, letting your pipes freeze in the winter?
• Or does it just oscillate wildly, a physical manifestation of a logic bomb, until the hardware gives up?

You've connected this whole Rube Goldberg machine to Home Assistant, no less. That's fantastic. So now the attack surface isn't just your thermostat; it's every other insecure IoT gadget on your network. Your smart lightbulb gets compromised, and now a hacker in a Romanian basement is using it to pivot and send precisely timed signals to your heat pump to induce catastrophic failure. You were worried about noise and inefficiency; I'm worried about your house being declared a superfund site after the refrigerant leaks.

And you think this will ever pass an audit? Let's just run through a quick SOC 2 readiness check, shall we?

• Access Control: Failed. You proved their support authentication is nonexistent.
• Change Management: There is no documentation for this "feature," so its behavior is undefined and uncontrollable. Any firmware update could change it without warning.
• Risk Assessment: You've gleefully documented a single point of failure that can cause thousands of dollars in physical damage, and you're calling it a "closely guarded secret."
• Security Monitoring: What logs does this "inference engine" produce? None? Shocking.

You're lamenting the lack of a standard protocol. A standard! How quaint. You think a standard would save you? A standard is just a common set of attack vectors we've all agreed upon.

You didn't find a clever hack; you found the smoking crater where a security design review was supposed to be.
