4. Input change not working

Input change not working

  • E

    Hi

    im getting the hang of the UniPi 1.1
    But i'm having difficulty changing the input state.
    Could anyone give a hand?

    #!/usr/bin/python3
    import http.client
    conn = http.client.HTTPConnection("192.168.173.209:8080")

    payload = "{"input":"1","circuit":5","bitvalue":"1",:"rising","rising":["string"],"counter":"0","mode":"Simple","modes":["Simple"],"ds_mode":"string (optional)","ds_modes":["string"],"glob_dev_id":"number (required)","alias":"string (optional)"}"

    payload = "{"input":"5"""bitvalue: 1""}"

    headers = { 'content-type': "application/json" }

    conn.request("POST", "/json/input/circuit: 1", payload, headers)

    res = conn.getresponse()
    data = res.read()

    print(data.decode("utf-8"))

    this is my code.

    this is the error message I'm getting.
    has anyone seen this?

    {"status": "fail", "data": "Input is malformed; could not decode JSON object."}

    Hi @Eanna!

    The error indicates that your message is not valid JSON. But first - inputs do not have an "input" state which could be changed; they are purely used for reading signals. Only outputs have an output state which can be set.

    Second of all: you should either delete or comment out (with ##) your fourth line, though this will not by itself fix your problems

    Third of all: you should be able to set the output with the following:

    import http.client

conn = http.client.HTTPConnection("192.168.173.209:8080")

payload = "{\"value\":1}"

headers = { 'content-type': "application/json" }

conn.request("POST", "/json/relay/1", payload, headers)

res = conn.getresponse()
data = res.read()

print(data.decode("utf-8"))

    Will this code change an input to an output?
    How would I do this?

    Thanks

    @Eanna
    Changing an input into an output is not possible

    Can I send a pulse or anything out?
    Or is this only through analogue pins?

    @Eanna
    You can use the relays to send a pulse out, or the analog output
