I think I have found the issue... The component that should connect the pin to the chip is not lined up properly and isn't making connection... I have to solder that probably...Hmmm, firstly check the battery conversion factor, from memory 191.??? do a quick google. If it's not that, then yes, it's likely the D1Mini is the issue. If that's the case you're better of replacing the D1Mini.
You could try and diagnose the D1Mini, there's a voltage divider on it in addition to the one on the iSpindel, could be an with the D1Mini PCB or with the ESP8266 itself.
The resistor to select the internal/external aerial is the one to the left of "rainsun", the ceramic aerial. In the picture vertical for internal, moved to horizontal for the external.The d1 mini has a component that needs moving if you are going to use an external antenna. I think that is the one you have loose.
But have you checked with the vendor re the issue as well, suggests poor QC if you have this problem out of the box.
@adrianoftyriel That's the correct baud rate, so you should be seeing the real info.
I'd suggest a reflash, but erase everything first, Brewflasher makes this step very easy!

Yes, and also look at the possible issue between the A0 and D0 pins... I don't have a D1MiniPro to hand to check the tracks, but that misplaced resistor could be the cause of your problem. Just don't short to one of the resistors next to it. See if you can unsolder from the right side (in your picture) first. If the resistor is then free, solder to the correct pads.
Good luck!
This is from the iSpindel FAQ page
- Can I operate it in a stainless steel container? Is it possible to get through the faradic cage?To achieve a sufficient WLAN signal strength you can do the following things:
- Break open the faradic cage. This is possible by electrically separating the lid from the pot. Can be achieved by applying a silicone sealant between the two parts.
- Use a passive antenna. Use a shielded cable that is stripped from both ends (i. e. Lambda/4), where one side ends in the pot, exactly 3.2mm. This is transmitted passively from the inside to the outside and vice versa. A good example can be found here: iSpindel - Aufbau und Betrieb - Seite 20 - hobbybrauer.de
- Install a wifi range extender next to the barrel to increase the signal level.
I have not seen that one before. Don't like the fact the WiFi module and hence antenna is nearly the middle of the board.View attachment 758343

Has anyone used this version of ISPINDEL PCB? Is this circuit board working properly?
有人使用过这个版本的 ISPINDEL PCB 吗? 它工作吗?
I've just got one that was built by the member here in the classified listings. Testing it inside my Anvi stainless steel fermenter, it reports great. No issues. My wifi is decent not super, but absolutely issues.My apartment isn't very big and I also have a MESH setup, so maybe it would just work. I have excellent WiFi reception throughout my apartment. I would assume that only if the signal from the iSpindle is super faint there would be any need to extend/amplify it.
I had the same question/worry. I just made a WiFi repeater out of an ESP8266 D1 Mini. It works perfect and only costs the few dollars of the D1 Mini.I'm planning to ferment in a stainless steel pot with the lid on and am looking for a way to find when fermentation has ended. The iSpindel looks like it could work well for this, except for the issue of blocking the signal. Is a range extender a reliable solution? It's really simple and doesn't require tinkering, so would be my preferred option.
