I think they want you to consider using the RAPT pill as the beer sensor ( another untested extra).
The temp probe is behind a small plastic grill in the right hand side wall about a third of the way up, interesting choice of location

Given the intended usage (temp controlled fermentation) of this product, and the accepted wisdom of measuring the liquid temp rather than air temp I find this whole add-on sensor thing a bit Heath Robinson, especially at its $900 price point, it's almost as if it's an afterthought or a MacGyver fix for a product that doesn't work as intended. Will be amazed if the Rapt V1.1 doesn't address this issue.
Thanks Mark - only problem ...no manual provided. Videos coming....but a manual would have been nice.
I has seen the hysteresis setting...but was sure if smaller setting or larger was better....no manual to look up.
The screen would show when fridge was cooling or heating. I get that mass of fermenter will be fairly stable ....but i hoped it wouldnt be too much to keep near or about the set temp.
I have since turned of fan setting - seeing if temp stabalises .....not sure if fan shoukd on/off......no manual...?

I thought you got the best control when you had both a beer temp and chamber temp reading? Like the brewpi does it. So from that perspective it does make sense to have the chamber probe where it is, but I agree, its pretty poor not including the beer probe.
I have no doubt this fridge will be awesome, just needs some tweaking and good customer support.
If you guys really wanted us to do this would could make the extended probe come as standard but we are also a bit worried that some customers may find that this looks a bit messy having a new product arrive to you with a long dangling cable that you may or may not want to use. Would be keen to get all your thoughts on this though. How many of you would prefer the neat probe integrated into the wall or to have the long probe pre-installed?
You mentioned that you had some temperature swings in the product. Have you got the updated firmware as this was one thing that was improved on a firmware release 2 weeks ago. Please go into the menu on the display and check for OTA (over the air) updates.
Firmware already up to date. Here's a screenshot of the temp. Up to 6 Oct the hysteresis was changed to 1 degree, and after that I reset it to the default 2 degrees for comparison. Any recommendations to reduce the temp swings and improve efficiency would be much appreciated.

How about using a 3.5mm socket for the probe, flush with the fridge wall? Connect the probe cable using a 90 degree 3.5mm plug. Quick and neat connection, space efficient and the 3.5mm connector will allow for rotation of the probe cable. In the grand scheme of things, this is minimal cost. Using a 3.5mm connector would also allow for the electrical disconnection of the probe built into the wall of the fridge. Although, I think it would be preferable to have two temperature channels and feed the algorithm with more data points, being the fridge temp and probe temp.
How would this additional temp probe differ from the Rapt pill?It might be worth noting that we have put a bluetooth chip on the RAPT fermentation chambers and at the moment this is not currently being used for anything but we will be using this more in future and the purpose and advantages of this will be come more clear in future as we continue to release firmware upgrades.
Right now we are also working on another wireless bluetooth probe. As low energy bluetooth is so efficient these days you can run a bluetooth probe in the fridge that is completely wireless and the battery will last years even with fairly fast sampling rate (every 10 seconds). So in this instance you could also purchase a wireless probe that you could sync with your fridge and then this would feed data back to the RAPT chamber. This data could be simply overlaid and displayed on the graph in the RAPT portal or it would also be possible to take this temperature reading to control the fridge to make the heating and cooling device turn on/off with the bluetooth probe rather than the integrated NTC wired probe.
So the RAPT fermentation chamber will act as a bluetooth gateway in future and so will other new devices that we sell too such as the BrewZilla Gen 4. For this same reason you would be able to use a wireless bluetooth probe and pair the probe with your Fermentation Chamber when you are fermenting then pair it with your BrewZilla Gen 4 when you are brewing beer for instance.
Elvis?I agree with you Grmblz, but I think the Rapt V1.1 is a bit optimistic. I would have thought that by now the brewing fraternity should know the first cabs off the rank in regards to product from KL is something to give a wide berth to. Elvis would have.
Some song he sang about it being foolish to rush in.Elvis?
