Sonoff RF bridge recent tasmota, door sensor -- only some events

Hardware
,
1

A year or two ago I got sonoff rf bridge (black box, model says just “RF Bridge”). Finally got to “deploy” it. Flushed recent tasmota (generic tasmota.bin) on it using tasmotizer while following some generic instructions on howto via USB, chose

But for the door sensor, I get only one type of event (Data is the same), so can’t tell when “opens” vs “closes”, and seems not consistently really:

15:18:40.526 MQT: tele/tasmota_sonoff/RESULT = {"Time":"2025-02-24T15:18:40","RfReceived":{"Sync":7970,"Low":270,"High":790,"Data":"D18651","RfKey":"None"}}

15:18:59.323 MQT: tele/tasmota_sonoff/RESULT = {"Time":"2025-02-24T15:18:59","RfReceived":{"Sync":7940,"Low":280,"High":780,"Data":"D18651","RfKey":"None"}}
15:19:17.258 MQT: tele/tasmota_sonoff/RESULT = {"Time":"2025-02-24T15:19:17","RfReceived":{"Sync":7980,"Low":270,"High":790,"Data":"D18651","RfKey":"None"}}

The sensor is ATM very close (1ft) to RF bridge.
any guidance/clues on what to do to get it reliably detect events?

Hello Yaroslav Halchenko,

The Data: portion will tell you what the action is.

You can look at mine to see how I do it. I use a python script based on option 2 in the bottom link, My HA configuration is here:

3

the problem I have is that I observe only 1 value for the Data so would not be able to tell on either it is about door getting opened or closed. Seems to appearing on when the sensor disconnects (door opens), but not when reconnects (door closes down).

4

A lot of 433Mhz door sensors only send a message when the door opens, not when it closes. Those are primary meant for intrusion detection, not for home automation.

This 433Mhz model sends distinct open & close messages (Imagesearch on Aliexpress for sellers)

Works perfectly and the single AAA battery lasts forever.

I use OMG on the Sonoff RF Bridge but you can use the same logic with Tasmota:

I can confirm that the Sonoff RF 433 Door/Window sensor ONLY sends an open event.
There is NO event from closing the sensor.
The Zigbee and WiFi sensors do not have this limitation.

I ran into the same issue and I still have 7 door/window sensors laying in my drawer and probably soon thrown out.

And be careful with the Chinese products.
The listed specs does not always correlate that well with the reality.
This is one of the places where it is often wrong.
