Re: open-drain (open-collector) on the input: is external pull-up necessary

See _P003_Pulse.ino Do you mean this?: pinMode(Settings.TaskDevicePin1[event->TaskIndex], INPUT_PULLUP); Anyway, thanks for your comments. Do you think it is good to report/request the pull-up/down issue to the https://github.com/letscontrolit/ESPEasy/issues/new ? In the Tasmota SW, for example, th...

Re: open-drain (open-collector) on the input: is external pull-up necessary

Since the counter plug-in does not have a pullup option you should install the external resistor. Couple minutes work, done Yes, until you have to do it 50 times :D I have made some experiments. Hardware Settings => GPIO boot states: PIN14 set as an input Devices => Task Settings: Device: Generic -...

I would like to configure: "Devices => Generic - Pulse counter" - but there is not setting/definition in the menu for pull-up/down...
