Strange behavior on GPIO inputs

[ArFurik]

I try to create a motion sensor with a NodeMCU ESP8266 v3. Your software is great and the JSON able to set all I want... but a strange behaviour occurs on the GPIOs used as inputs. I tried several GPIOs and the problem is the same :

• When the input switch to hight, the signal is detected, I can see a led lighting ans the Home app say the a motion is detected. The itching at 7 returns all theses states to 0 -> OK
• If an other 1 is applied during the 2 seconds (approx.) after, all of this good behaviour repeats -> OK
• If an other 1 is applied more than 2 second after -> NOTHING, but the following 1 at the input is well detected, no matter the time elapsed then.

The detection seems done once in two.

I tried several GPIOs, I tested with a physical switch or my motion detector, putting or not pulldown resistors. This strange behaviour is exactly the same in all the cases. I spent a lot of time trying to adapt the JSON, without solving the problem. I sought on the net if this could be an electronical behaviour from the ESP or the NodeMCU, but nothing about that. So I think it is a software issue.

Thank you in advance for your help, the JSON used is paste below.

{ "c": { "l": 13, "b": [{"g": 4,"t": 3}] }, "a": [ { "0": { "r": [{"g": 12,"v": 0}] }, "1": { "r": [{"g": 12,"v": 1}] }, "t": 12, "i": 7, "f1": [{"g": 14}] } ] }

try this JSON - {"c":{"o":1,"l":2,"i":1,"b":[{"g":0,"p":1,"t":1}]},"a":[{"t":12,"i":5,"f1":[{"g":12,"p":0,"i":1,"t":0}]}]} which PIR model are you using? do not forget that esp8266 need PIR to use 3v.

Hi, it's a PIR HC-SR501. No problem with it and its output is a TTL signal 3.3v. I tried both with a switch or the PIR and it is exactly the same behaviour. I will adapt your JSON to my GPIO config and try.

It's work !!! Thank you Uldis Some little things are not understood in the JSON commands yet for me. I put this JSON : {"c":{"l":13,"b":[{"g":4,"t":3}]},"a":[{"0":{"r":[{"g":12,"v":0}]},"1":{"r":[{"g":12,"v":1}]},"t":12,"i":7,"f1":[{"g":14,"p":0,"i":1,"t":0}]}]} The difference is on the f1 section : "f1": [ { "g": 14, "p": 0, "i": 1, "t": 0 } ]

• "p":0 -> So it seems that a pullup resistor is the default and I must indeed disable it.
• "i":1 and "t":0 -> This is more mysterious... Why may I have to invert the input signal... Well in this case, with i and t, it could be double-inverted and so it works.

Whatever, all works now perfectly, and I thank you very much. I spent a lot of time on this before posting a issue.

happy to help!!!

"i":1 is triggering motion sensor when input is low. if you use "i":0, then triggering will be when input is back to high which is when motion sensor gets back to no motion sensed. so with "i":1 motion message appears almost instantly.

"t":0 also for me is not 100% clear, but @RavenSystem pointed it out in one of opened issues and it helped. i think it is replacing boolean used in older HAA versions.

Ok, I'll keep that in mind for my future HAA projects. Have a nice day.
