If anybody else is looking for a fairly quick way to do this, I set up a Node-RED flow that could be executed periodically (weekly?) to retrieve the latest firmware versions from Opto22’s website. Right now, I’m retrieving a list of versions for products I care about and simply printing a Javascript array to the debug window, but once the retrieval and formatting is done, you could send the latest version to MQTT, a database, a variable, etc.
This is a quick, down and dirty flow. No error checking. No request status code checking. Those things wouldn’t be too bad to add, but I didn’t do it (yet).
The data (msg.payload) I’m retrieving looks like this in the end:
[
{
"product":"GRV-EPIC-PR1",
"version":"3.6.0"
},
{
"product":"GRV-R7-MM1001-10",
"version":"3.6.0"
},
{
"product":"GRV-OACI-12",
"version":"1.3d"
},
{
"product":"GRV-IMAI-8",
"version":"1.3f"
},
{
"product":"GRV-IRTD-8",
"version":"R1.3e"
},
{
"product":"GRV-IVI-12",
"version":"1.3f"
}
]
My flow has a function node in the beginning with a function block containing the definition of the list of products:
msg.firmware = [
{
"product": "GRV-EPIC-PR1",
"url": "https://www.opto22.com/support/resources-tools/downloads/groov-epic-processor-firmware",
"version": null
},
{
"product": "GRV-R7-MM1001-10",
"url": "https://www.opto22.com/support/resources-tools/downloads/grv-r7-mm1001-10-firmware",
"version": null
},
{
"product": "GRV-OACI-12",
"url": "https://www.opto22.com/support/resources-tools/downloads/grv-oaci-12-module-firmware",
"version": null
},
{
"product": "GRV-IMAI-8",
"url": "https://www.opto22.com/support/resources-tools/downloads/grv-imai-8-module-firmware",
"version": null
},
{
"product": "GRV-IRTD-8",
"url": "https://www.opto22.com/support/resources-tools/downloads/grv-irtd-8-module-firmware",
"version": null
},
{
"product": "GRV-IVI-12",
"url": "https://www.opto22.com/support/resources-tools/downloads/grv-ivi-12-module-firmware",
"version": null
},
];
return msg;
Here is the Node-RED flow:

The flow does use a node from node-red-contrib-loop, so that needs to be installed in order to run this flow.
