THis issue of no numbers and the dreaded ??? gets more curious:
This story gets more curious, the more I delve into.
I was finding in last months, that the appearance that my sensors were dropping out due to failing exactly 7 days - mostly ??? !
the more I checked , I found that no, sensors were still functioning correctly as long as I got out of my condo a 100 feet and found receiver would recover after about 30 minutes and then accurate readings would come back on . As long as I stayed out of my condo, receiver and old sensor started working fine again.
I also found that while in my condo when the fun erupted - readings dropped to 100 at speeds that body cannot do, if I walked out of condo, and got away from my condo, I would see the following:
a) receiver would go to ???. Antenna status would disconnect and then reconnect.
b) While out of condo, I would cause a disconnect of receiver and then let it recover and stayed away till back up.
c) amazingly now 3 weeks later and multi-times , I have repeated this nonsense and recovered the sensor/receiver pair and got accurate readings.
d) after recovery, during this interval of interference in my condo, as long as I kept my receiver in my car trunk/ refrigerator and took out when I left my condo, there was no problems with it on old timed out sensor(restarted)
I find this all very unacceptable, intolerable.
My sense is that:
Some interfering RF signal close by in my unit was emitting sufficient power to override my sensor/transmitter pair.
Some how my receiver was loading incorrect erroneous data causing drop to 100. I would see the antenna staus on receiver suddenly disconnect for no known reason and if I walked outside away from unit, it would re-connect properly and run.
When I walked out of my condo and got far enough away from interferer, my receiver would see valid restored reading of my transmitter that was way different from previous garbage loaded in my condo and declared the sensor bad ???.
Staying out of range of interferor, allowed the receiver to recover and then go back and display correct data. ( About 1/2 hour.)
Is this acceptable - no!
One thing driving me nuts is why this crap goes on in my 6 unit condo site while in fact out of here, performance is actually fine for a rf linked device, outside up by condo lot swimming pool, in car, driving around, in the mountains around here near the beach.
I have even walked around my 6 set townhouse-condo building with an excellent rf field meter set and find that looking out from our building set, I see little and mostly quiet, but looking into our building set I see high energy leakage that shouldn't be there.
The other curiosity was that if I caught a fast drop just as it started by walking out, receiver sensor pair would immediately recover back to path it had been on and continue fine with no ??? . I would also see an antenna status change although receiver had been within 2 feet.
I do not know how the rest of you good folks cope with this kind of grief?
