By chance is your beer temperature still changing during these initial hours (by more than a couple degrees?), or do you pitch yeast only after you have stabilized temp? It looks like kegland doesn't have any temperature correction algorithms setup so while the density of the wort changes so do the readings, and thus they can swing in that time. My extended test with water had me throw it in the fridge and leave for several hours to make sure the recording was working through metal, so as the temp of the water dropped, I saw a corresponding drop in gravity (20f drop saw a 7 point drop in gravity). I'll have to do more brews, but I also suspect you get a weird spike around the time that the yeast start to get active and currents begin to develop in the beer.
I would bet a large amount of money that it is still tenaciously hanging on to the AP you initially connected it to and that is why you are getting super infrequent updates, and that would also likely explain why you see it's signal strength as weak. This isn't meant to be a mobile device so it wouldn't have been programmed to switch connection points. I’ve seen a lot of devices that don't seamlessly switch to the highest signal strength AP in meshed networks and it really wouldn't be a use case Kegland would be thinking about with the product. In the product troubleshooting section they list “wifi connectivity issues due to unusual network setup” as a likely cause of not getting recordings after initial setup, and suspect scenarios like yours falls under that. At your first opportunity I would pull out your pill and reregister it in the room you plan to use it with the AP it will be connecting to. Mine is about 20 ft from my router with a wall, a closet door and a fridge door between the two, and I've not had any connection issues with it.
So far, I have been happy with my first ferment. I do think I will run a calibration on it after this is finished to try to get it closer in readings to actual (it was 9f off with water test and 12f off with this ferment), but the temperature logging has been very accurate and I suspect that outside of the starting offset the fermentation track has been accurate as well. When taking the offset into account I should be almost at my finishing gravity now, so I expect to see minimal/no further changes (reading 1.016, expected fg is 1.003, so 12 pt offset would be 1.015), and of course will confirm finishing gravity with a hydrometer to verify that it kept the offset from start-to-finish. I've been increasing the heat by a degree at a time as fermentation goes on in case anyone was wondering about the gradual creep on the temp graph line.
