Hi
Is it possible to use a RF Remote 433MHz to activate sonoff ihost security mode?

Thx

Yes, but with Sonoff RF Bridge. Note that there are two versions available. The newer seems to be much better.

I am getting a lot of cross reaction of buttons and only some of the buttons work on my remotes:

  1. 2/4 work
  2. 4/4 work
  3. 2/4 work
    The RF system all went bonkers a few weeks ago and it has been odd since. If I didn’t have RF already I’d have gone for Zigbee buttons only - I’ve never had them cross react or only partially work and several are from other manufacturers.
    The RF Bridge also has a local mode but no local only mode whereas Zigbee buttons added locally definitely act locally.

It can also be done with an eWeLink compatable switch that has an integral RF receiver. There are plenty of cheap switches around- Sonoff and non Sonoff. You would just then need 2x simple scenes (1 auto and 1 tap to run) that when the switch is toggled ON by the RF Remote it switches the switch back to OFF and then arms iHost. You would only want to enable those scenes when you go out. As an alternative or additionally a lot of video doorbells feature an RF transmitter to operate a remote sounder- you could use that signal to arm iHost’s security alarm. You go out, press the door bell button and the alarm is armed. It would be good practice to have some external light or other indicator under iHost control that flashes say once to confirm that the security alarm is armed. Using the doorbell RF signal means that if you are away and iHost isn’t armed then anyone that pushes the doorbell button would arm it. For reasons of secuirty I would advised that iHost is only armed by RF. To disarm more securely from outside it’s best to do it via cast.
