Is that a tilt or reed switch I see for the reset?Did you build it yourself? How one of mine looks for comparison in case a component is in the wrong way round.

Yes it is a reed switch, means that I can trigger it or adjust it when in the fermenter. ie change interval / turn off. Still works as normal. Useful if I've got something that's a real slow burner such as a Brett Saison. First few weeks had it hourly then as activity slowed turned it to 12 hourly. Slight fiddle to install but managed it fine.Is that a tilt or reed switch I see for the reset?
Yes, I've tried a few screwtop test tubes but they're either too big or too small. The thought I had to make a mini iSpndel, is based on a ESP12F and that governs the PCB size and the minimum tube size. I'm not sure what the float angle is going to be like compared to the Petling but I'm going to continue to hunt for a suitable container. I have the PCB down to just over 20mm, although I haven't yet got any made, waiting for a container...Have you looked at lab supplies and test tubes for your narrower container?
If you go for a slim device, consider ESP-03, it is only 13mm wide. Have a few less pins, but enough for iSpindle
Too bad I just chequed ESP-03 lacks analag input, so no battery voltage monitoring. Not good.I've got test tubes, but couldn't get the electronics small enough to fit. Over the next few days I'll have a detailed look at the dimesions and if it works I'll source some ESP03s to test. Thanks guys!
Ah! That's not good ,but thank you for checking. I'd be happy to solder a wire onto the ADC input of the chip, that does not mean that everyone is. I'm going to stick to the 12F for now and keep looking a smaller container. Slow burner project!Too bad I just chequed ESP-03 lacks analag input, so no battery voltage monitoring. Not good.
I'm currently thinking yes it is? I recharge when I get down to 3.5V or so. I get a couple of months or half a dozen brews out one charge (so far).Would the battery monitor be that important?
Yes to try and maintain battery health and yes I will continue to look for a suitable container/capsule.@ChrisThomas
Is that because you don't want to do full charge and discharge cycles on the battery to prolong it's life?
I agree a shrunk version would be useful, I want a smaller one to fit through the openings on keykegs which I ferment in sometimes.
Yes it will but you'll miss all data in between connections, it will only send the data of the moment it connects to WiFi successfully. I would recommend installing a WiFi range extender in your garage, then the iSpindel will always have a connection to the extender and the extender with your WiFi in the house.I'm hoping someone can answer my question. I brew in my non-connected garage and my wifi is in the house. The wifi works just fine in the garage as long as the garage door is open. My question is, after losing connection, will my ispindle auto connect to the wifi when the wifi is available in that area?

Thanks, sounds like that's what I need to do.I had a similar situation, my wifi was hit or miss in the garage which is where I brew and where my fermenters are. I added a wifi range extender in the garage and it solved my issue, both ispindle’s stay connected with no issues.
It could be either some issues related to wifi connection (takes a long time) or the device is not going to deep-sleep properly.@ChrisThomas Thought it might be.
One that would fit in those yeast bay bottles would be the perfect size for my key keg fermenters.
Currently I'm trying to work out why one of my ispindel is losing 0.01 v per half hour and it's only signalling every half an hour. Brand new battery and tried another battery as well. No lights on and was working normally before but now excessive power loss.
When it was on every 15 minutes it lasted 36 hours and at half hour intervals with another battery lasted 52 hours very odd.
Not sure how to identify this issue anyone any ideas?
