On a different topic, regarding the Ebyte modules, I'm noticing that they are much more likely to miss a packet if being run at 2.1v than if it's being run at, say, 3.3v. I've tried this now on two different modules, and the results are repeatable. It's a preliminary result, because so far I've only tested it with respect to the "listen mode."

I had thought it would somehow automagically select the better antenna for receiving, but it looks like it wants me to make that selection myself. So, this may work better with longer preambles I suppose, to give enough time to measure the RSSI on each and then decide.
I suppose an easy solution would be to have a remote node send repeated packets, and I just program the RFAxis to toggle between its two antennas after allowing sufficient dwell time per antenna. That way it's more likely to receive at least one of the packets.
All in all, though, I think maybe having two separate radio receivers (since they're cheap anyway) for a gateway is probably better than having one radio receiver, with the burden on the firmware to select which antenna to receive on.
Any thoughts on this?

@NeverDie but how will you spend all the time you save by not having to create new boards all the time?
Yeah, not just that, but also not having to waste all that time waiting for each new board to come back from the fab. 
I just noticed a very clever thing that Fanstel did: their nRF52 modules all have the same land pattern and pinout. That means you can upgrade from a regular nRF52832 to a power amplified version, or even an NRF52840 (when they become available), by just dropping the upgrade module into the same position on the PCB. i.e. you can run all the different modules from the same PCB design. Pretty cool. I like it.
Dean Roddey also observed a decline, and he had a plausible explanation for it: http://cocoontech.com/forums/topic/30720-fewer-home-automation-postings-whats-behind-it/?p=258683
Nice job! Looks very dapper.
Alternatively, you may (?) be able to plug your screen directly into the I2C connector used for the TH sensor on:

Depends on the pinout, of course.
@Jokgi
Thanks! Yes, those three tables are exactly what I was looking for.
Just which pins on the nRF52832 are connected to which control pins on the RF Front End. I just now checked with a continuity meter, and it looks like none of them are. So, it would appear that I'll need to wire the pin connections external to the PCB, which is weird, but maybe that's just how it is.
