Correct temperature: Fineoffset-WH2, ID: 183
Wrong temperature: Fineoffset-WH5, ID 183

With rtl_433 parameters -R 0 -R 18:no-wh5 you can filter out all WH5 messages.

It looks like sensor with the same ID is treated as a single sensor (at least when ...

You should capture the rtl_433 log on the rtl_433 device and change the rtl_433 code so it does not send corrupt data
See running discussion there: https://github.com/merbanan/rtl_433/issues/1964


I think I should be able to redirect the output from rtl_433 simultaneously to a file and to ...

My RFLink has difficulties receiving updates from a sensor which is behind two walls. rtl_433 seems to get all updates but shows faulty temperatures. RFLink has higher gain antenna. Due to limited space rtl_433 receiver and RFLink are about 40 cm away from WiFi access point.

It might be an issue with rtl_433 then...

But you cannot compare a RFXCom transceiver (or RFLink) with a USB stick that was not designed for supporting weather sensors.

I do think it's a great project! But I know that RFXCom does some sensible checks inside

This is also not a Domoticz issue, it ...

I compiled the latest code for rtl_433 and added the same sensor by RFLink. rtl_433 shows an erroneous temperature value but RFLink does not show it.

@mpx2, throw away that temperature sensor? If it reports false values it is of no use.
If your device is to far away from the 433Mhz transceiver, try a bigger antenna


I have Telldus 313160 (FT007TH) temperature/humidity sensors https://forum.domoticz.com/viewtopic.php?p=212188#p212188 ...

Is there a simple way to add median filter for temperature sensors? My 433 MHz sensors someties report erroneous values, very high or very low. I would like all my sensors to use the median value of the last three measurements, like median(t0,t1,t2).

Update: The problem is not Xiaomi related. Same problem with Osram plug which worked ok before updating plugin which required updateting Domoticz to beta version.

Yes the USB TTL was broken, again!

I bought a Xiaomi WXKG01LM wireless switch https://www.zigbee2mqtt.io/devices/WXKG01LM.html

The problem is that the text log is always empty. The Switch Type is set to selector by default. Last seen value is only updated if the selector level changes. Consecutive single clicks won't update the last ...

What is your setup ? what is your OS distribution ? How is the ZiGate connected to the PI? Which version of PI are you using , what model of Zigate to you use ?
If you are on a PI4, I think that you MUST use not use the USB3 port


I reinstalled everything.

Zigates USB-TTL has broken two times. This time the LEDs will turn on but Raspberry Pi won't detect Zigate. Dmesg will report these errors.

When I updated to 2020.1 RFLink stopped working. I abandoned Domoticz because all I have had is problems.

Now I had some time and I updated Domoticz to version 2020.2 (build 12211) and I got RFLink working.

I had the same problem with switching on all those electronic devices, it even trips my 30mA earth leakage circuit breaker several times.
That is why I purchased a UPS. ;)


What is your UPS model? There's not much filtering in basic UPSs. Online UPSs with high quality sine wave are very ...

Toulon7559. Do you know which electronic devices cause interference? You can add filters for those devices or try to use different phase.

Schaffner IF13-SE-H05-3100-WF-XXX dual stage filter is another alternative to filter mains

Generally, Raspberries are susceptible for the quality of their power supply.
Therefore, for my 'production' Raspberries the Power Supplies are 'original' and/or bigger capacity than required.

Still the impression that these Power Supplies (occasionally) transfer the transients from the 230V ...

I added a delay just before the for loop.
os.execute("sleep " .. math.random(5,15))
This will cause a random delay between 5 and 15 seconds. dzVentz script is not triggered at 00.

This will work for switches triggered by other time based scripts but ( although unlikely ) it might fail for ...

The script has been mostly working ok but some times it fails when repeat and switch on happens at the same time.
At 2020-01-01 16:00:02 my switch turned on and immediately was turned off. The switch state is off so the next repeat is off command.

Unfortunately there is nothing dzVents can do ...

I have a simple AC switch which uses 433,92 MHz and uses one way communication. I need a LUA script which will repeat on or off command every 10 minutes until on or off is pressed.


Using dzVents it would look like below.

When not yet familiar with dzVents please start with reading Get ...

is there anything like this for wifi that works with domoticz?
would love to have a weatherstation but do not want to buy an rflink just for that.
