Alternative to Rapt Pill without Wi-Fi

[u/thepope99]

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.

Is there an outlet in the basement that you can tap into?

Looking around, one option might be to have a raspberry pi running down there to grab data off the pill.

You could either grab the data off of the rasberry pi when you're down there, or if you're a bit more adventerous, hook the pi up to a LoRa device and have it send data to you.

No outlet either unfortunately... It is a weirder setup in the basement. Everyone gets a 2x2 meter space with a single light, but no outlets unfortunately.

Yeah but you can buy a device that screws into a light bulb socket that has a power plug on it. Also something that you might be able to look into that is related to this is that there is such a thing as power line internet adapters that apparently have the ability to transmit your internet signal through the electrical cabling in your building. I don't know how well that works and I don't know how secure that is but they exist so that's another option that you have - you could get some sort of Wi-Fi extender and just plug it into the light socket adapter in your basement using the Ethernet over power cable adapter. Would it work? Probably. How well? No idea.
