RF-433

433MHz reception worse than ever

Hi! I’ve been using Homey for approx 6 months or so, and while I’ve been fairly happy with the product, I don’t feel that it meets it promise with 433MHz reception. The outlet I’m controlling (outdoor, 5m from Homey) seems to work fine, but my Oregon Scientific sensors are gone. They are all within 7m, but behind a wooden wall. One is outside. 
I’ve never lost any of them during 3 years with RFXtrx433, but I lose them several times a day with Homey. This has not been better over time, it’s actually just gotten worse. At the moment none has answered for 2-10 days!

I’d like to use them to control outlets for my room heaters, but I can’t trust that Homey won’t lose signal when it matters. 

I’ve read that the problem is because it needs to support 433-434 MHz, and therefore it doesn’t work properly. Is this necessary? All my devices are CE certified, and seem to be pretty much dead on 433.92MHz. Isn’t this the standard Homey should focus on? 
If cheap knock-off brands can’t be work because they’re not using the correct frequency, then why try to support them?

    This is a known issue for 1.5.6, Athom chose to release 1.5.6 without support for the oregon-sensors:
    https://github.com/athombv/homey/issues/2075
    and
    https://github.com/athombv/homey/issues/2023

    But, there is no correct frequency, just a different ;-)
  • Wow, that is dangerous!! 
    What if I were to use those sensors to control my heaters?!

    I was mainly purchasing Homey because of the 433 support, so I hope this will be fixed, and hopefully get a good signal in the future.

    as CoCo / KlikAan mentions in their manuals in English an Dutch 
    (and I think you must extend that to all unreliable signaling )

    Never use COCO products for life support systems or other applications in which equipment malfunctions can have life-threatening consequences.

    So Yes! dangerous!  

    Even when it works ~99,99 % of the time good, 

    it fails ~53 minute a year so enough to burn your house down.

    (And yes I also hope the 433 sensitivity for receiving will be better)

  • Man... 
    Yeah, I've lost all signals at the moment, so waiting for that update. Will be nice to get temps from my rooms again. It's summer now, so all heaters are disconnected anyways.
