I performed an update today to the newest nodered OS image.
I took a OS backup using the service mode, to be safe
I took a file copy backup of /home/unipi and /etc
I flashed the new image
boot into the new image
set timezone

$ sudo timedatectl set-timezone Europe/Brussels

installed latest updates

$ sudo apt-get update $ sudo apt-get upgrade

updated unipi firmware:

$ sudo /opt/unipi/tools/fwspi -u 1 -v -P -U

Stopped node-red

$ sudo systemctl stop node-red

moved /home/unipi/.node-red to /home/unipi/.node-red.old
copied /home/unipi/.node-red and /home/unipi/node_modules from the file-backup to the current system
rebooted unipi

Node-red came up with correct config. Inside Node-red I had to update the @unipitechnology/node-red-contrib-unipi-evok node-palette to v0.0.8 and then had to replace all unipi-evok inputs and outputs by their respective unipi-evok-v3 counterparts.
After that everything seems to be up and running again. (apart from my 1Wire temp sensor which seems no longer be detected by Evok.. but that is out of scope here, I assume)

Possibly you may have to configure more and or re-apply changes you did on previous OS image. (I had to also install and configure mosquitto mqtt for example.)

Hi @iVar,

All images must be in the Resources directory, otherwise they are not available, please see screenshot.

@Martin-Kudláček Hi
After a long time of trying and many tutorials, I made it
to switch my relays on my Unipi 1.1, to read temperatures and everything with ModbusTCP and Nodered. When I see it now, it's very easy, thank you for the great board and the software.

No new posts.

Hi my project is fully functional thanks to you all

Hello Thomas

Exemple with L503, xS51 and xG18. I also have some
DS18B20 on the 1Wire Bus.
Install Steps:

Check if everything is configured and works correct in evok Check output of <IP_of_Neuron>/rest/all in your Browser Install FHEM from the repository (https://fhem.de/#Installation) Connect FHEM with your Neuron by typing: define <Name> Neuron <IP>:80 set attributes like in the picture (see on the bottom) below

After that all inputs and outputs get recogniced automatically.
You will get a room named NeuronPin with all devices.

Example (with some changed names):

Example of a analog input with a PT1000 Sensor for Temp. mesurment:

Example of a analog input with a Honywell PX3 pressure sensor:

I am developing a control system with FHEM for my distillery with a heat recoupling for the building heating of the residential house. When I'm finished, I'll be glad to present the project to you.

Hi,

just for reference and to help future questions:

I am running OpenHAB on a dedicated RasPi. It is a Java application which I do not want to run on a Neuron. Keep it simple and stupid.

In C code it was not too complicated to get data from OpenHAB though curl calls.
See code snipplet:

/* Function gets calledd with an item name */ /* The url is defined here globally: */ /* url="http://openhab.domain.com:8080/rest/items/" */ long get_2file(char *url, char *filename ) { CURL *curl_handle; FILE *FI; int r,code; code = 0; curl_handle = curl_easy_init(); /* set URL to get here */ curl_easy_setopt(curl_handle, CURLOPT_URL, url); /* disable progress meter, set to 0L to enable and disable debug output */ curl_easy_setopt(curl_handle, CURLOPT_NOPROGRESS, 1L); /* use default write function */ curl_easy_setopt(curl_handle, CURLOPT_WRITEFUNCTION, NULL); /* open the file */ FI = fopen(filename, "w"); if(FI) { /* write the page body to this file handle */ curl_easy_setopt(curl_handle, CURLOPT_WRITEDATA, FI); /* get it! */ r = curl_easy_perform(curl_handle); if (r != 0) { code=-1; } else { /* Data is now in the file */ } /* close the header file */ r = fclose(FI); } else { code=-1; } /* cleanup curl stuff */ curl_easy_cleanup(curl_handle); return code; }

Hi @RobRemote,

Unfortunately PiDome is in a bit of a state of flux right now (without a stable version in fact), which makes it difficult to recommend a specific solution. If you are still struggling with this issue you may be able to cobble something together with EVOK and WS-to-MQTT plugin posted on the forum.

Apologies for taking so long to reply,
Kind Regards,
Tomas
