Thanks, that should not happen / it should accept all types in JSON.
I'll fix this soon.

Which version were you running? And if so, can you give these binaries a try?

homepoint_release.zip

Sorry I do not have the hardware anymore to run the tests

Hi' @sieren

I have (out of curiosity) tested with a text string as JSON attribute (ON or OFF) to be read.
This also crashes and force Homepoint to reboot.
Probably identical issue.

I run the 'September special' m5stack_full.bin version.

This example below reading a light state will crash Homepoint:

{
    "name": "TEST",
    "type": "Sensor",
    "icon": "door",
    "devices": [{
      "name": "TEST",
      "type": "singleValue",
      "firstIcon":"door_small",
      "jsondata": true,
      "firstKey": "state",
      "getTopic": "zigbee2mqtt/Office bed lamp"
    }]
  }

Ciao !

Hi' @sieren

Just downloaded and retested with Hp v0.05 (ESP_generic) and no crashes now reading non numerical JSON attributes 🙂🎉👍

Can read the state for eg. a light entity or whatever and it turns up nicely on the display.

One issue though:
In one of my tests I wanted to read the state of a light entity.
state attribute is returned, but its not the correct state attribute that is shown on the display.
Displayed state attribute is found one level down in JSON string.
The returned attribute is the state for update key which is idle.
The expected state attribute shown is ON

{"brightness":251,
"color":{"x":0.491,"y":0.39},
"linkquality":110,
"state":"ON",
"update":{"state":"idle"},
"update_available":false}

{
    "name": "Test json data",
    "type": "Sensor",
    "icon": "door",
    "devices": [{
      "name": "test",
      "type": "singleValue",
      "firstIcon":"wattage_small",
      "jsondata": true,
      "firstKey": "state",
      "getTopic": "zigbee2mqtt/Office desk lamp"
    }]
  }

Also tested with a boolean attribute returned.
Homepoint didn't crash but just shows 0.0 for both true and false attributes.

Could be nice if booleans was converted to On/Off or perhaps a different binary text expression (Yes/No, Out/Home, Open/Closed etc.) :-)

{"battery":100,
"illuminance":24,
"illuminance_lux":24,
"linkquality":55,
"occupancy":true,
"voltage":3005}

{
    "name": "Test json data boolean attribute",
    "type": "Sensor",
    "icon": "door",
    "devices": [{
      "name": "test",
      "type": "singleValue",
      "firstIcon":"wattage_small",
      "jsondata": true,
      "firstKey": "occupancy",
      "getTopic": "zigbee2mqtt/Office"
    }]
  }

Ciao !

I think you've found a bug. Can you verify by updating your firmware with the OTA part (or flash from the ground up) ?
Attached a build to test.

Hi' @sieren

Just made a quick test on the M5stack using OTA file.(last tests was made with the ESP_generic files)
Didn't know what to check for - so I tested for both issues reported :-)

Still crashes reading a true or false boolean value from occupancy json key.

MQTT publish: topic 'zigbee2mqtt/Office', payload '{"battery":100,"illuminance":0,"illuminance_lux":0,"linkquality":55,"occupancy":true,"voltage":3005}'

If i send a non valid boolean [truuuuue or falllse] or whatever it doesn't crash. So json key is parsed by HomePoint for sure.
Retested on 'standard' v0.05 and found that it also crashed on M5_stack_OTA ?
It didn't crash yesterday testing with ESP32_generic v0.0.5. Very strange...

state attribute read is also unchanged. Still shows idle attribute from update: {"state":} json key and not the expected ON attribute.

MQTT publish: topic 'zigbee2mqtt/Office desk lamp', payload '{"brightness":227,"color_temp":370,"linkquality":92,"state":"ON","update":{"state":"idle"},"update_available":false}'

Should I retest using the ESP32_generic files or are you confident that outcome should be identical ?

Ciao !

[sieren]

Oh boy, yeah, apparently the M5Stack build failed after the build script refactoring in #132

Here's another build, this time specifically test for these two issues:
a) Should display "true" or "false" instead of crashing when a bool value is retrieved
b) Top level "state" key should be displayed

homepoint_release.zip

[htvekov]

Hi' @sieren

That was a quick fix ! 😁

Nothing much to say than both issues are now solved 👍

Issue a)
true or false displayed ✔

Issue b)
Top level JSON key is displayed (ON or OFF for that specific state) ✔

Regarding issue b)
It could be nice to be able to specify a nested JSON key attribute to be retrieved by adding the full path.
I have some sensors that provide nested JSON attributes with identical key names.
It's quite typical for combines temp/hum/pres sensors I believe.
I've no idea about what the syntax should be or what parsing capabilities you actually have in HomePoint ?
(Not really into nested JSON's 😉)
e.g.

{
    "name": "Test json data",
    "type": "Sensor",
    "icon": "door",
    "devices": [{
      "name": "test",
      "type": "singleValue",
      "firstIcon":"wattage_small",
      "jsondata": true,
      "firstKey":  "\"update\":{\"state\"}",
      "getTopic": "zigbee2mqtt/Office desk lamp"
    }]
  }

Thank you, Matt.
Much appreciated 🙋‍♂️

Ciao !

[sieren]

Can you provide me an example of the JSON Data there?

I might not get to this in the near future. Looks like the Zigbee2MQTT/HA Stuff is more important than this particular case?

[htvekov]

Hi' @sieren

Sure thing 👍
I have several sensors that use nested JSON's. I'm afraid that it's quite common.

Outdoor lux sensor:

{"Time":"2021-01-13T14:39:33","BH1750":{"Illuminance":421}}

Greenhouse temp/hum/press. sensor:

{"Time":"2021-01-13T14:37:30","SI7021":{"Temperature":3.4,"Humidity":96.8,"DewPoint":2.9},"BMP280":{"Temperature":4.1,"Pressure":996.3},"PressureUnit":"hPa","TempUnit":"C"}}

I have no issue with these at the moment.
I can always send the needed data from Home Assistant via MQTT if needed.

I agree that the Z2M /HA stuff is much more interesting for other users than me 😉👍

CIao !
