Posted November 2, 2026 at 1:30 pm · in A home heating station in the 3D designer: rooms, heat pump, buffer tank and cylinder #2

I want this for my own house. Heat pump, buffer tank, cylinder, almost exactly my setup. Can I do it on a hobby account?

So my ESP32 boards will get a Settings tab? They’re on MQTT with my own firmware.

Moved the wire to 34 and it reads 1480 with WiFi on. Never would have guessed that, I’d spent two evenings on caps and attenuation. Chart looks like a soil chart now.

3.3 V from the DevKit pin.

That was it. Static buffers and it connects first time on all five boards. I’d also been building the host in setup() exactly like you said, which explains the random reconnect failures I’d been blaming on my Wi-Fi. Thanks Laura.

Got a resistor from a friend, moved red to 3V3, enabled the overlay and the 28- folder appeared. Probe survived the 5V. Basement is 17.8, which sounds right. Kept the CPU one as a separate key, might be handy.

It does but it’s the CPU chip temperature, that’s why 52. It’ll never be room temperature inside the case.
