RFXtrx433 problems after upgrade to 2020.2

[MartinO]

Dusted off an old 2015 Domotics install on Raspberry Pi. Originally running Domoticz 2.x and RFXtrx433 f/w 243.
Could not get my KaKu lightswitches or temp sensors to work. First upgraded RFX f/w to 1025. Then at least my temperature sensors showed up at the RFX. (These ones https://www.banggood.com/DANIU-433MHz-W ... rehouse=CN)

Decided to pull the plug on the obsolete install and did a fresh install of Domoticz 2020.2 with associated Debian version on the Pi.
On this install the RFXtrx433 does not recognize either the temp sensors, nor the KaKu switches.... Tried all settings and protocols, reloaded firmware, etc. To no avail.

To my surprise the RFX picked up some lighting switches overnight... Probably from the neighbour. Hope I did not scare them when playing around with these. But anyway... any suggestions where to continue looking to fix the RFX problem with my stuff?

Solved.

RFXtrx433 appeared to be the E version, changed to different firmware (Pro 1, rev 1043). That fixed the temperature sensors.
KaKu units appeared to be ELRO which required special attention:

Passed this level, going to the next....
