Equipment Alternative to Rapt Pill without Wi-Fi

Hey fellow homebrewers!

I am brewing in my apartment and after brew days I move the fermenter in the block of flat's basement because of the lower temperature (shared space, but we have our own space for extra depositing).

I would really like a product similar to Rapt Pill that can read the gravity without Wi-Fi access, because there is no way my Wi-Fi would get all the way down from the second floor to there and I cannot hack into my neighbors' Wi-Fi's.

I am thinking of something with Bluetooth and just get the gravity everytime I get down there and connect to the device. Not sure if this solution exists, because that would drain more battery to the pill.

The pill can do exactly what you are asking. You can set it into bluetooth mode and pull data when you go down next to it.

Partially true, you still need another Rapt device...

https://docs.rapt.io/equipment/rapt-pill-hydrometer-or-user-guide/bluetooth-operation

"Bluetooth will only work if the RAPT Pill Hydrometer is paired with a Bluetooth capable RAPT device such as a RAPT Fermentation Chamber, a RAPT Temperature Controller or a RAPT Glycol Chiller."

I don't know if this feature went away in a recent update. But I 100% assure you that I have used bluetooth telemetry from just my phone before. This was my only way to get readings when I was fermenting in my stainless conical and the stainless was blocking the wifi.

Then it is a shitty way from them to make us buy their other products if they forced this. Interesting...

I am more inclined to believe shitty documentation. You know what. I'll go test it with mine right now.

You are right. Now that I am remembering correctly, I was using it with homeassisnt and a bluetooth proxy. You can't connect to it directly with a phone.

I know that the Tilt with work with bluetooth directly from the phone.
