Updated the ESP-IDF from 4.4.0 to latest 5.1.1 and rebuild. Framework updated automatically to framework-arduinoespressif32 @ 3.20004.220825 (2.0.4) Test with 2 sensors on the same pin : Works fine. However there are two no blocking error messages: E (1275) gpio: gpio_isr_handler_remove(480): GPIO isr service is not installed, call gpio_install_isr_service() first Complete startup messages: 163 MCO:BGN:INIT GW,CP=R-NGF---,FQ=240,REL=255,VER=2.3.2 168 MCO:BGN:BFR 169 NM:INIT:VER=1.9-dev 171 NM:INIT:INO=Testcontroller v1.0 174 NM:INIT:LIB VER=2.3.2 CP=R-NGF--- 178 NM:BFR:INIT 1310 GWT:TIN:CONNECTING... 1313 GWT:TIN:IP: 192.168.68.28 1317 MCO:BGN:STP 1335 NM:STP:ID=0 M=0 1340 NM:LOOP:RELAY(1):SET t=2 v=0 1359 NM:MSG:SEND(2) t=42 p=2864B875D0013C99 1392 NM:MSG:SEND(3) t=42 p=28920675D0013CB4 E (1275) gpio: gpio_isr_handler_remove(480): GPIO isr service is not installed, call gpio_install_isr_service() first E (1276) gpio: gpio_isr_handler_remove(480): GPIO isr service is not installed, call gpio_install_isr_service() first 1407 NM:STP:HW V=0 F=240 M=49480 1421 NM:LOOP:RELAY(1):SET t=2 v=0 3424 MCO:REG:NOT NEEDED 3426 MCO:BGN:INIT OK,TSP=NA 3429 NM:MSG:SEND(1) t=2 p=0 3968 NM:LOOP:2864B875D0013C99(2):SET t=0 v=22.75 4537 NM:LOOP:28920675D0013CB4(3):SET t=0 v=22.19 4542 NM:MSG:SEND(2) t=0 p=22.75 4545 NM:MSG:SEND(3) t=0 p=22.19

Thanks @fredswed and @gomba777 I've added to the roadmap the capabilities you are referencing to from https://www.mysensors.org/build/pulse_water so the align with NodeManager's. I'll likely come back to you once the development will get to that point for reviewing the implementation if you don't mind. Thanks

Sorry for the delay first of all, unfortunately I didn't get the notification of this thread If you are using a latching relay I'd recommend using SensorLatchingRelay1Pin or SensorLatchingRelay2Pins which should take better all the aspects of a latching relay. Then you can still use the safeguard for closing the door after a given timeframe. And yes you have to set a reporting interval even if not intuitive at all. This is because the safeguard is checked in the loop cycle which is called only if a reporting interval is set. So if you have a safeguard set to 1 minute, the report interval should be 1 minute or less. Thanks!

Referencing the enhancement request on https://github.com/mysensors/NodeManager/issues/233 Thanks!
