Jeroen,

Where is the tutorial mentioned under 1:?

First need to find again an active TTN-Gateway:
the one within reach apparently has stopped ..........

Forces me, either to find an (interim?) solution with the KPN-Network, or to build/setup my own TTN-Gateway.
The latter solution obviously would not be bad, as contribution to the Community.

advise to get a RAK831, great gateway with an external antenna I've got a range of 20km.
Great stuff from TTGO and connections to domoticz.

You need to use the same privilege settings as you would when using MQTT to connect to the TTN network.
Did you try using a MQTT client ?

Hi Gizmocuz,

Is it possible to implement GPS?

At this moment quite a lot of people try to find a functional connection for uplink from TTN to Domoticz:
example thread from another forum.

Just try to understand how they do it, and then 'translate' for own application .........

[Toulon7559]

Not yet getting data visible at TTN's Console.

Then trying alternative approaches to get LoRa-message from an End-Device to an Endpoint-URL
Is somebody at this Forum familiar with Beeceptor?

With my Marvin>KPN DeveloperPortal>MendixDashboard I created a forward rule which uplinks messages to Beeceptor, but then obviously the question:
what next to get the message in the direction of MQTT-link to Domoticz? With the data in an appropriate format for 'easy transfer'?

In the perspective of KPN'S DeveloperPortal the following aspects seem of some importance:

Requirements of your Application Server
LoRa data is forwarded to an application server of your choice. The application server can be any public URL on the internet and can be your own server or somewhere in the cloud. In order for the application server to work properly below items are required:

Application Servers must have a valid SSL certificate
Receive, send and decode HTTPS POST messages from public internet
Check and generate SHA-256 hex signatures

In this 'picture' the MendixDashboard is such Application Server, and also Beeceptor could play that role.

I tried to get TTN LoRa hardware to work. Everything works except that Domoticz shows only one measurement of tree.
(Every six (Temp/Hum pairs) measurements shows ok in cayenne dashboard)

TTN console Application Data Fields:
{
"relative_humidity_3": 32,
"relative_humidity_4": 31,
"relative_humidity_5": 25.5,
"temperature_0": 22.1,
"temperature_1": 21.1,
"temperature_2": 20.6
}

Domoticz Console:
2019-04-19 08:58:25.666 TTN_MQTT: Topic: lopy4modulit/devices/lopyblu/up
2019-04-19 08:58:25.674 (TheThings) Temp (lopyblu)

Devices list shows tree lines:

Seems that Domoticz shows only last received measurement.

Another possibility is to use one of the standard integrations in TTN, "HTTP Integration" (https://www.thethingsnetwork.org/docs/a ... ions/http/).

This will send the whole payload of the Lora Device as a json message to a website you define.
I use a simple PHP server where I created a php page, that captures the json message and using some json decoding getting access to the entire payload with all information in it.

When you have found the actual variable you need, just use the DZ json option to send this to DZ. (http://IP:PORT/json.htm?type=command&param=updateuservariable&.....)

Advantage of this is, you have full control over all information send from the TTN Lora device and the php file gets triggered automatically when the device sends something.
Then it is up to you if you want to send it to DZ or first check if the device was changed and then send it.

What can i do with lora network ??
Only weather sensors?
Or also a motion?

or?



Some have a hardware setup?

[HeTi]

Now using mosquitto_sub it's easy get one measurement out in ttn-mqtt server:

Code: Select all

]mosquitto_sub -h eu.thethings.network -t '+/devices/+/up/temperature_1' -u 'eka' -P 'ttn-account-v2.isz' -C 1

Just look your access-key in your application page in ttn-console.
Simply use inside script to but http --> Domoticz.

Still waiting Domoticz own hardware implementation reconize different measurements in CayenneLPP messages.

Can you provide a demo of the script we can use with mosquitto included?
Need some help

[kiddigital]

From Domoticz 2020.2 the TTNMQTT module is greatly improved and it is now easy to get your Lora TTN data into Domoticz.

See this Wiki page for more details.

Hi

Old topic...
Only i will give lora a try..
Some advice for a good working gateway?
Diy or buy?
What type?
Where do i llok foor the special differents?

[kiddigital]

Buy a good outdoor gateway and you can cover a large area.

Sensors can be anything and DIY.

Good luck and have fun building…

[Toulon7559]

Rainy day (and more rain promised) is good argument to revisit Lora.

Check before trying experiments:
has the Domoticz-implementation for TNNMQTT been upgraded for TNN_V3?

Good point... I will have a look how easy/hard it is to switch from v2 (supported till end 2021) to v3... looks doable

[Derik]

V3 is the new so a must for the new gateway...
Only what hardware do you have?
Is there a good DIY option?
Or better to buy a good brand?
Why multichannel?
Why webui? or do all the gateways needed a webui?

Hope you will help a noob in lora


Edit...
Are all the ttn devices supported bij Domoticz
So a ttn motion is a motion in domoticz, etc etc?

Best/easiest is to buy a ready to use LoRa gateway, one that supports TTN (which most do), and Sensor wise you probably look at something either out-of-the-box or DIY (or combined).

Domoticz supports retrieving data from TTN and therefor does not have/need direct hardware support for LoRa. The TTN takes care of all the hardware/messaging/etc. and makes the data available through standarized MQTT messages. The TTNMQTT module 'connects' your Domoticz instance to these MQTT message and retrieves them for you. Depending of the details available in the data the module will try to determine what type of Sensor the data is coming from (temp, rain, etc.) and otherwise put the data into a 'generic' sensor.

Hopefully that clarifies things. (btw, you can start with some simple equipment you can buy from The Things Network like a gateway and simple node or arduino-type dev board).

[Derik]

Thanks

I read a lot.
When i have time i buy a gateway.

Do you have some advice? gateway and interen or extern antenna?
