"ERROR: cannot find a OneWire Temperature Sensor! " The error occurs when the temp probe cannot be found, it will cause the iSpindel to boot loop. There are a few general causes for it. Generally, it is from the solder joints at the back of the temp probe, piercing the battery casing and...

I'm not sure what you mean by the on position, if you're referring to the switch, it's relatively obvious as the gyro LED will be on when the iSpindel is on. Correct, the 0 ohm resistor needs to be moved into the green position if you find you are not getting enough reception. The antenna you...

The diode is generally removed to avoid issues with using the USB on the Wemos whilst having the iSpindel turned on and also powered via battery. This is the reason I suggested that it's not really needed as you can't really "accidentally" power the Wemos independently, given the rotation of the...

I don't think you need to worry about the diode, especially with the USB port for the Wemos pointing downwards and not generally accessible unless you remove the PCB. You do however need to swap the 0 ohm resistor from the vertical to horizontal position in order to enable the IPX port -...

only thing I can think about is a different cable, hopefully one which sits a little more loose-fitting

Ideally you need to follow the rest of the instructions on GitHub for a multi-point calibration and then configure the polynomial in the iSpindel. If you get it close to 25° in 20° C water, you will still need to do the polynomial. The 25° angle is just the optimal angle to get a more accurate...

Completely normal behaviour. Once configured, the device runs every 900s only. It’ll connect to your wifi, send stats then go back to sleep. There’s no functional reason to have to reconnect whilst it’s in a brew and it allows the battery to last 4+ weeks. To go into config mode, you need to...

Best bet is to remove the battery and power the larger board (Wemos) via USB from a computer. You'll need a program like Termite (baud 115200) if you are using Windows. This will show you the debug output from the device each time it wakes up, letting you know why it is likely failing.

@RRising yep, just sent you a PM. There hasn't been too much movement with the iSpindel project in the last few months. The major release 6.2.0 almost completes all outstanding items. It is quite a mature project with plenty of online resources and advice for anyone wishing to obtain parts...

Just sent you a pm with all the info.

Sorry for the super late reply. I don't get emails from this forum very well :/ I can send you a kit locally if you haven't already sourced all the parts you're after.

Hey Mike, what sort of troubles are you having? The PCBs should have screening on them to show which components go where including direction. He has shared a PDF in one of the past build versions as well, still quite relevant. Are you using any specific version...

I always get spares in which are free. If you contact me I can organise to send two spares out for the cost of postage $2.20 and the little CD case box from AusPost $1.50.

I would double check your startup logs. It might be crashing due to a missing OW sensor (your temp probe). It's a common issue which causes a reboot loop and can be because it's around the wrong way, a dry solder joint or faulty.

You might need to force flash mode by bridging D3 and GND on boot. I've had a few get upset with my messing around too much and I've had to resort to it.
