The tube that turned out not to be PTFE is a nasty surprise. On the fan side, if you run Klipper: heater_fan only switches the fan on above a temperature, it can’t tell that the fan is unplugged. A fan with a tachometer wire and tachometer_pin set at least shows you the RPM, and you could add a macro that pauses the print if it reads zero while the hotend is hot.
The low-tech version is to look at the heatsink fan spinning after any toolhead work, before the first heat-up. Cheap habit compared to rebuilding a melted toolhead.





The comparison table is the useful part, because “optional and replaceable” is something you can actually check. Remote access works without the subscription through your own reverse proxy, a VPN like WireGuard/Tailscale, or a tunnel, and the Alexa/Google voice integrations can be set up manually, just with more steps. So the no-lock-in claim holds for the service itself.
The rename seems mostly aimed at the confusion they mention, where new users thought “Home Assistant Cloud” meant running Home Assistant in the cloud. Fair enough given how many people ask exactly that.
