Morning
Hope you’re all having a good christmas in the cold regions. We are boiling over here.
I have been playing around with labels on my seedlings and plants for a while, because it’s simpler to see when/what/etc. This post almost ties in with [my previous question about tracking/visualising data](https://farmos.discourse.group/t/how-to-see-and-feel-data-also-merry-xmas/1821/4), and it might solve one of those problems.
However, I want to start using QR codes to track changes on FarmOS for plants/pots… What is the best way to handle this, if you’ve done anything like it?
If I link to a log, this obviously won’t work, and the page for a single log is not useful to track a plant or seedling, or tree. If I link to the record page for it, it is a somewhat static and cumbersome clicking around. My only idea is to link to the asset’s logs [/asset/96/logs]. It’s not easy to read, data sanitisation is off depending on how people _title_ the logs, etc, but it will work.
Any other ideas or ways you use it? And if you don’t, let this post and a cheap thermal printer be an idea for your next splurge.
Have a good festive period, and thanks for making FarmOS awesome.

I use qr-codes to create some logs with the help of Node-Red.
Some info here:
[My Node-Red and FarmOS project - #34 by pat](https://farmos.discourse.group/t/my-node-red-and-farmos-project/1341/34)
The qr-code takes me to a http-endpoint node, where the url is parsed, and actions are taken.
I only create logs with this. But I bet there’s other useful cases too.
I also had Node-Red to create logs for me if I send email to a certain address, and mark it with the Review flag. Then I can add resources, other flags etc later.

That is quite nice. I am yet to try Node RED, and it will help a lot.
I have established a tag ID system (6 digits) for tagging and QR’ing plants and trees in the wild. I might steal your idea there on the email and location.
Thanks for the link. Value in information.

You’ll get addicted 🙂
There’s quite a few posts about it here on the forum. @Farmer-Ed got me going, and he’s made som nodes to connect for farmOS.
So once you get going there are some working flows you can look at.
One thing I like very much is the possibility to create quite complex logs with just a tap on a button.
