Signals lost because of Byron SX overload?

[mjdb]

I find that about 1 in 10 on/off switching-signals are lost, both incoming and outgoing.
The orange receive-light of the RFXtrx433E blinks every few seconds.

In the device-list I see over 20 Byron SX Chimes with varying ID's and Units (like 0000 - 0; 0000 - 4; 00FF - 15 etc). They are continuously updated.

The log of ID 0000, Unit 0 shows for example:

2017-01-12 13:44:20 On
2017-01-12 13:44:14 On
2017-01-12 13:44:09 On
2017-01-12 13:43:40 On
2017-01-12 13:43:32 On
2017-01-12 13:43:13 On
2017-01-12 13:42:45 On
2017-01-12 13:42:03 On
2017-01-12 13:41:24 On
2017-01-12 13:40:47 On
2017-01-12 13:40:12 On

Could this be some real device (from a neighbour), or is it some noise that is wrongly interpreted as Byron SX Chime?

Can this be the cause of loosing the switching-signals?

How can I get rid of them?

It could be noise. The Byron SX protocol does not have a checksum and it is therefore not possible to suppress these messages.
For normal use deselect: Setup - Setting - Accept new Hardware Devices

Thank you Bert for your quick answer.

I selected accept all on all protocols to find the source of the continuous blinking receive-light on the RFXtrs433E. That is when the ByronSX came up.
For my system of course it is noise.

Can some other (defective?) system with my neighbours be mistaken for ByronSX? Or should that realy be a real ByronSX device?

I have the same!

My Byron SX doorbell is detected by RFXCOM but it detects two and three devices:
