Ghost switch ??

[Nemocaledonie]

Good morning all,
There you go: I'm trying to do automatic watering with ESPEASY.
The assembly consists of 2 relays mounted so as to reverse the polarity to open or close a solenoid valve.
It works well, except that ... from time to time I have a valve opening without any action. I give you the Rules that I use.
I looked everywhere, using other switches: same. without switch: same. And the whole thing is random. Change the Wemo :same (it's a Wemos D1 mini Pro)
If anyone had a clue, she would be welcome.
Thanks.
Xavier

This is a typo?

Also please check if the ESP may have crashed and rebooted when the valve opens unintended.
If the unit reboots, then some pins may toggle a few times at boot.
See: https://espeasy.readthedocs.io/en/lates ... on-esp8266 and especially the links mentioned there.

And you should really use a pull-up resistor (10k or 4k7 would be fine) on the button input gpio, the internal pull-up of the ESP is too weak to keep it firmly high if the button isn't pressed, so any induction across the wires may fake-push the button.

@ epost : Sorry for the bad typo, bad copy / paste.
@Ath : Good idea for the resistance in external pull-up, I will do that. I thought the internal resistance was enough.
#TD-er : Thanks for the link ( I lost it ) ; I tried with different Wemo D1 mini Pro (V1.0.0), and always had the same result. The weird thing is, nothing happened until I used the "Rules".

Anyway, I'm going to try @Ath's method and put an additional 10K or 4.7K resistor (I have both). I'll let you know.

Thanks a lot. Have a good day.

Thanks for that hint. I'm also experiencing a "nervous" D1 mini Pro which toggles an input after it's own mind . Have always used internal pull-up, but this time it's with a ~1m cable and a push-button.

Ah, you're experimenting with a very nice antenna mounted as GPIO random generator input

Problem solved: it was a small resistance problem :/
Thank you so much.
The only thing that I changed since yesterday apart from adding a resistor is that I use the D8 (GPIO 15) with a pull-down and adding a resistor of 4K7 (of course ) because I noticed that the TTP223 mounted in pull-up (A closed) does not work permanently (it goes off and you just have to disconnect the ESP for it to restart). I did not find on the internet if it was normal so a little bit of soldering iron and hop in GPIO15.

Have a good day.
