I "made" a floating (zwave) swimming pool temp probe

I would also like to know the settings used to get the reporting interval to 15 minutes :slight_smile:

Were you able to find a similar device or a spot to order the FGK-101? Looks like amazon.com is all sold out now as well.

23

Check out this from Climax in Zigbee and Z-Wave:

That does look like it might work, but I don’t see them actually being sold anywhere. I just found on other boards they only deal B2B with a minimum order qty of 100 pieces. I only need 1 :stuck_out_tongue:

I’m just about to order poolsense. On the face of it, it looks outstanding and only about £150. It reports temperature, chlorine and pH, all via sigfox (some kind of satellite iot) so no connection concerns. It’s a ball that floats in the pool made by a South African company. There is also home assistant integration. I can’t see any comments from users but we’ll worth a try.

Brilliant idea!
I have the same pool floater…
Since you posted long time ago…

Whats the right, good way to do this nowadays? And is also cheap?
Not willing to spend much for that.
Preferable with zigbee protocol

hi, which zwave gateway do you use for this sensor? an usb zwave dongle or an zwave gateway?

I found on Amazon one of the older versions of the fibaro sensors with the contacts in them but I have yet to get any device handler working that works with the contacts on the new Smartthings app, anyone have any luck with it? The Fibaro built in handlers do not work at all so I found a generic zwave handler that is a door window sensor with temp and the sensor part works but not the temp probe.

29

I did manage to buy a Fibaro FGK-101 Zw5 Door / Window sensor and connected a DS18B20 temperature probe.

How can I get the temperature to be displayed and tracked? It does not show up in the entity list. I tried expluding/including the device, even a reset of the door sensor.

The temperature probe seems transmitting the data, it just doesn’t get displayed/tracked.

When I dump the nodes data I can see:

{
        "id": "7-49-2-Air temperature",
        "nodeId": 7,
        "commandClass": 49,
        "commandClassName": "Multilevel Sensor",
        "endpoint": 2,
        "property": "Air temperature",
        "propertyName": "Air temperature",
        "type": "number",
        "readable": true,
        "writeable": false,
        "label": "Air temperature",
        "ccSpecific": {
          "sensorType": 1,
          "scale": 0
        },
        "stateless": false,
        "unit": "°C",
        "list": false,
        "value": 31.25,
        "lastUpdate": 1631284388795,
        "newValue": 31.25
      }

I can also see the temperature in Z-Wave JS → Fibargroup (node name) → Multilevel Sensor (7-49-2-Air temperature] Air temperature).

Why would HA not pick this up and display in the dashboard. I would like to track the temperature changes as well.

I am using the latest version of HA.
Any advice would be appreciated.

Same thing here, no more display of temperature with fgk101. It worked few month ago, but i had to reinclude the module recently and since that, no more temp and a lot of “unknow” sensor in entities…

Hi,
Nice idea. I wonder wouldn’t Shelly Uni be easier to setup?

@bestermanus I managed to get the temperature data into HA this way:

sensor:
  - platform: mqtt
    name: "Pool Temperature"
    state_topic: "zwave/nodeID_7/49/2/Air_temperature"
    device_class: "temperature"
    qos: 0
    unit_of_measurement: "°C"
    value_template: "{{ value_json.value }}"

Your nodeID very likely will be different.

First I made sure my mosquitto mqtt broker is up and running and then I inspected the messages.
