mqtt.iotguru.cloud has IPv6 address in DNS, but refuses connections on IPv6

harald — Mon, 06 Feb 2023 15:23:58 +0000

I am trying to add a connection to my IoT MQTT Panel in Android. I get an error "Unable to connect to server ...(IPv6 addresses) and ECONNREFUSED".

Testing from my workstation;

$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable
$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable
$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable
$ telnet -6 mqtt.iotguru.cloud 8883
Trying 2a01:4f8:1c1c:13f8::1...
telnet: Unable to connect to remote host: Network is unreachable

It looks like the App in Android doesn't switch over to IPv4 after getting a connection refused on IPv6.

I suggest that either the IPv6 AAAA-record should be removed from DNS, or better, get IPv6 answering on the service.

API functionality

OnPa — Tue, 05 Oct 2021 14:07:10 +0000

Hi,

I'm trying example with sending data from ESP32 to IoTguru, unfortunately I'm receiving error with DNS resolving API address...

Do you know, what is wrong ?

Example - https://github.com/IoTGuruLive/theiotguru-arduino-library/blob/master/examples/02_send_measurement/02_send_measurement.ino

1050009: {sendHttpValue(nodeKey, fieldName, value):223} - ENTRY
1050009: {sendHttpValue(nodeKey, fieldName, value):225} - Send request to the cloud
hostByName(): DNS Failed for api.iotguru.live
1050017: {sendHttpValue(nodeKey, fieldName, value):234} - Response received from the cloud (status code -1)
1050026: {sendHttpValue(nodeKey, fieldName, value):236} - EXIT

Thanks,

Hi,

Is there a way to copy the Dashboard config to a new mobile device? (as it is not stored in the cloud)

Thanks!

Update multiple fields of same node

Varun — Wed, 11 Aug 2021 11:11:08 +0000

Hi,

Using rest API how can I write the data to multiple fields of the same node?

Like I want to write the temperature and humidity fields that are in the same node.

Device selection is missing when we create a new chart

Dunaparty — Mon, 08 Jun 2020 12:37:30 +0000

Hello,

When we create a new chart on the dashboard, we need to select the node name, which can be problematic if we use the same node names across multiple devices.

Thanks!

Get chart image over HTTP GET request

Dunaparty — Mon, 08 Jun 2020 12:33:39 +0000

Hello,

It would be great to get the rendered chart image (in png format) over HTTP GET request.

As I see we can download the image using the chart option, but I guess it os more like a JS magic, instead of an API call.

Thanks!

Relocate big widgets on the dashboard

Dunaparty — Mon, 08 Jun 2020 12:24:55 +0000

Hello,

For me it was pretty hard to relocate big widgets on the dashboard.

If I create a new widget, it is put at the bottom end of the dashboard. When I try to drag it higher, there's no option to insert it between two existing widgets, we need to create space in advance, which is quite difficult using big widgets (even on FHD screen).

I would recommend to allow to drag a widget to another one, which will insert the dragged widget above the existing one, e.g. existing and everything below would be pushed down to create enough space for the dragged one.

Thanks!

Android app: option to disable title on the chart

Dunaparty — Mon, 08 Jun 2020 12:18:01 +0000

Hello,

As you can see in the attached screenshot, on the Android app an additional title is rendered on the top of the chart area. An option is needed to disable that text to reduce clutter.

Each widget has an own title anyway, that should be enough.

Thanks!
