First of all many thanks for sharing the code, i've been following your project for long time but i just now started to do something. So, as in object i tried to control the nodemcu with mqtt and i got in the arduinoIDE serial monitor the "parseObject() failed" error. Can you help me to fix it?

Thanks in advice!

This is likely to do with HA sending the bad JSON string. If you monitor what bruh/porch/set is receiving with a tool like MQTTLens to you might be able to solve your problem

many thanks @timmo001 for the reply. I managed to get it working only in HA directly, because i really don't know why with mqttfx and publishing just the same words as HA outputs, it keeps giving the "parseObject() failed" error.

But thanks anyway, i will probably use it as intended.

i got the same problem..i dont even know what im i doing on mqtt ,im all lost

Same problem, can't get past "parseObject() failed" with MQTT lens or Home assisant. Related to that, can't get Home assistant to even send a MQTT message (with the "Services" tool)

{"entity_id":"light.bank",
"transition":"50",
"brightness":255,
"effect":"rainbow"
}

dosent show up in MQTTlens at all. HASSIO Config:

light:
  - platform: mqtt_json
    name: Bank
    state_topic: "bank"
    command_topic: "bank/set"
    effect: true
    effect_list:

With MQTTlens i can publish to "bank/set, with "parseObject() failed" as a result, so i guess the NodeMCU is OK so far.

"Message arrived [bank/set] parseObject() failed"

Any hint as to where i should start looking?

[sladaar]

well, i'm sorry to say that i got it to work but now some time has passed and i don't rememer how i did it. I think it could have to check that topic and message are correct, then a workaround or another NodeMCU code (or another esp8266, esp32, or better sonoff with tasmota which is easier) to get HA and mqtt to work. If i remember correctly the problem was with the payload, which has to be different from the one a mqtt sniffer reads. Don't remember why tho! Sorry to be not much helpful.

[Baloowozzy]

no problem, every options i worth exploring. and you seem to be on to someting with the payload. the nodemcu responds to this payload sent from MQTTLens:

  "state": "on",
  "color": {
    "r": 255,
    "g": 255,
    "b": 255
  },
  "brightness": 255,
  "effect": "solid"

And from what i can gather, the formatting looks like this sent from Home assistant:

{
  "brightness": 255,
  "color_temp": 155,
  "color": {
    "r": 255,
    "g": 255,
    "b": 255,
    "x": 0.123,
    "y": 0.123
  },
  "effect": "colorloop",
  "state": "ON",
  "transition": 2,
  "white_value": 150
}

Can this possible be the problem?
