Sonoff Mini with PIR HC-SR501 as Switch1n

[Calin Balanean]

Hi all,

Just curious if anyone has tried using the PIR HC-501 with Sonoff Mini.

I powered PIR from Sonoff Mini's 5V. Then I hooked up the ground to S1 and PIR data to S2. I configured GPIO4 as SWITCH1n and set a rule to set POWER according to the switch state.

The problem I'm having is a LOT of false positives. It just bounces back and forth.

Here's just the latest few minutes log: 

17:57:50 RUL: SWITCH1#STATE performs "POWER 0"

17:57:50 MQT: stat/sonoffmini1/RESULT = {"POWER":"OFF"}

17:57:50 MQT: stat/sonoffmini1/POWER = OFF

17:57:56 RUL: SWITCH1#STATE performs "POWER 1"

17:57:56 MQT: stat/sonoffmini1/RESULT = {"POWER":"ON"}

17:57:56 MQT: stat/sonoffmini1/POWER = ON

17:59:14 RUL: SWITCH1#STATE performs "POWER 0"

17:59:14 MQT: stat/sonoffmini1/RESULT = {"POWER":"OFF"}

17:59:14 MQT: stat/sonoffmini1/POWER = OFF

17:59:21 RUL: SWITCH1#STATE performs "POWER 1"

17:59:21 MQT: stat/sonoffmini1/RESULT = {"POWER":"ON"}

17:59:21 MQT: stat/sonoffmini1/POWER = ON

18:01:34 RUL: SWITCH1#STATE performs "POWER 0"

18:01:34 MQT: stat/sonoffmini1/RESULT = {"POWER":"OFF"}

18:01:34 MQT: stat/sonoffmini1/POWER = OFF

Not sure what I'm doing wrong.

Thanks,

Calin

The 'n' option is no pullup and you may be getting noise. I believe the device goes high when it sees an object so switch1i would be the correct setting.
