How many RF 433hz sensors (PIR, door sensor, etc) can be connected to Sonoff RF Bridge if it has been flashed with Tasmota? Afik. default Sonoff RF Bridge can only connect to 4 sensors.
As well BroadLink RM Pro+ , tried contacting them but no response.
What about Raspberry Pi with cheap RF receiver?
As far as sensors go, i do not believe there is an actual limit. You are thinking switches/remotes, which is different. As far as remotes go, you can increase the limit via a file before compiling the bin and flashing, i think the max is 16, i could be wrong, as i only use my bridge for relaying sensor states. I mostly use espurna.
So far i have 13 sensors sending to my bridge. Door, movement etc. The bridge will just relay the mqtt messages to hass and you do as you will from there.
Surprising Sonoff’s firmware only have 4 max on their Bridge then, atleast that’s what they said to me.
I’m still waiting for my Sonoff gear so I haven’t been able to experiment yet. Saves me some money/time not getting more receivers.
I assume you’ve got Sonoff RF Bridge, any reason you went for espurna in stead of tasmota?
More of a personal preference. They are both great.
