happy with this #iot #homeassistant compatible shelly humidity and temperature #sensor
Got it to post on my #mqqt server yesterday the way I want.
It has a local webserver you can access via its AP mode. Shuts down after a little while automatically. Does updates of its firmware. You can run it without cloud.
Nice for measuring the temperature of the attic. Runs on 4 batteries or usb-c

It has taken me about 12 minutes to cool down an 18650 battery which was heating up, that it was almost too warm to the touch. The battery was in the charger which clearly doesn't properly communicate with the BMS, creating a fairly dangerous situation
The battery in someone else's hand could have spontaneously combusted into flames igniting the charger and then the wood of the table it was standing on.
I have a habit of standing up, way in the depths of the night, either because I want to go training on my race machines, or because I want to physically feel how warm the batteries are that I'm charging.

Today I'm very glad that I routinely do this, because the BMS failed, a temperature sensor is obviously absent in the charger, and the chemicals would have potentially created a runaway situation because the battery was running this hot for at least a couple of hours!

The 18650 cell delivers the energy that is needed just fine it just cannot charge to 100% anymore

Of course I have marked the cell, so I can now manually remove it from the charger

#3DPrinting annoyance...

I have an #FLSun #V400 delta printer. A few upgrades, including to stock Klipper. I'm happy with it.

The issue: it's got a filament runout sensor up at the top of the print volume, right after the filament comes down through the top compartment of the printer, which houses the MCU and stepper motors. That works fine for detecting the end of a reel of filament.

But it's basically useless for detecting a filament break, because every break I've had has been between the sensor and the effector/hotend. The sensor happily indicates "filament good" while the hotend uses the remaining ~50cm of filament and then continues to print nothing, while cooking the leftover plastic in the hotend.

What do others do about this? Should I be moving the runout sensor to the effector, just on top of the extruder? Or I've seen what appear to be fancier sensors that detect filament movement, rather than being just a simple presence switch. Anyone have any experience with those?

I appreciate any thoughts from the more-experienced printers in the fedi. Thanks!
