RFXcom not working after some minutes

[Matthiasfr]

Hi,

I configured the transciever to work with 'klikaanklikuit' switches. This is working fine when I boot up the raspberry pi. After approximatly 10 minutes, I cannot control the switches anymore with domoticz. It is yust not reacting anymore (the virtual switch in the software is switching, the physical switches not).Someone who recognize this problem?

Thanx in advance

Matthias

The source of the problem is in most cases a bad quality power supply connected to the Raspberry PI, see chapter 21.3 in the RFXtrx User Guide.
Check if the RFXtrx starts working again after:
- disable the RFXtrx in Domoticz,
- disconnect and reconnect the USB cable,
- enable the RFXtrx again in Domoticz.

Nothing to do with the disconnect problem:
- Note that the RF noise of 107 is much too high. For a good receive functioning you should have a figure between 85 and 95. Do not locate the RFXtrx and USB cable close to other equipment including the RPI.
- Do not flash the RFXtrx433XL using Domoticz!!!

What do you mean with 'flash'? You mean updating firmware?

Problem stays the same. Now 90dB noise, still after some minutes the switches do not turn on or off. When i disable the antenna in the hardware section en re-enable it, it doesn't show any number for the noise, so it seems that on that moment there is no connection between the raspberry pi and the antenna.

Tried different power supplies, nothing worked. Also, when the transciever works, I see lights flashing when I switch. When it's not working, domoticz still says 'switching', but the lights do not flash on the RFXCOM.

Connect the RFXtrx433XL on a Windows system, use the same USB cable and check if the RFXtrx433XL keeps operating.
- If it also stops on the Windows system contact support rfxcom.com
- If it keeps operating follow the instructions given in chapter 21.3 of the RFXtrx User Guide: use a good quality power supply on your Raspberry PI or use an USB hub with dedicated power supply.

This seems to work. I will try a powered USB hub.

Hi,

I'm currently using this power adaptor: https://www.amazon.de/-/en/gp/product/B ... UTF8&psc=1
this cables: https://www.amazon.de/-/en/gp/product/B ... UTF8&psc=1
and this hub: https://www.amazon.de/-/en/gp/product/B ... UTF8&psc=1

After some days, it still happens that the rfxcom transceiver fails. Domoticz shows that it cannot connect with the rfxcom. Anyone an idea how this is possible?

Looks like I had(have) the same issue with my powered USB hub. Now I moved the RfxCOM back to the pi with 3A supply, and everything else is still on the externally powered hub. This seems to work now.

Further I created a dummy device to turn the Rfx hardware on/off twice a day using a timer on this device. Not a real solution but it did the job for me.

On action in device:

Code: Select all

Off action in device:

Code: Select all

http://192.168.178.55:8080/json.htm?type=command&param=updatehardware&htype=1&port=%2Fdev%2FttyUSB-RFX433&extra=&name=RFX%20Transceiver&enabled=false&idx=2&datatimeout=0&Mode1=0&Mode2=43&Mode3=0&Mode4=13&Mode5=5&Mode6=0

I found the above commands using "Developer tools" in Chrome, and searching for json whilst changing the hardware from active to inactive.
