I’m considering making a smart bale counter for recording bales as they are made with farmOS integration to increment inventory levels, the same counter can be left in the tractor cab to decrement inventory levels as bales are consumed also. The plan is to use a microcontroller and small LED display.
I’d be interested to hear other peoples thoughts on microcontroller integration with farmOS, I’ve a few ideas but open to suggestions.
Creation of long life authentication tokens for devices with limited input, (possibly not that desireable)
Lightweight webserver on microcontroller for entering configuration and credentials, (nice but complex and resource limitations of microcontroller may be an issue)
Use an intermediary server, such as Node-Red to handle Authentication, (Probably simplest option and already implemented on farm)
Use Data streams some how?, (its a bit more than the usual sensor project and will probably need some form of 2 way communication, but could possibly be worked out with a module that responds after receiving data.
Current Inventory Levels / (estimation of supply in weeks based on current livestock inventory??)
Have been thinking a bit more on this recently and started using @Symbioquine’s Asset-Link for tracking bales being consumed. So far this is on my phone, but I’m planning on getting a 10" Android Head-unit for the tractor. The built in browser can easily run Asset-Link but it’s also possible to install Node-Red directly on the unit which opens up the possibility to interface the tractor and mounted implements using ESP32 or similar microcontrollers. Running on Android : Node-RED
Note: Asset link is still in development and not yet recommended for production
Still undecided on a head unit for the tractor, most I’ve looked at are unknown brands with questionable hardware specs or running dated Android OS versions. So this may end up being phone or tablet based with a decent cab mount.
I started experimenting on my phone and installed Node-Red locally which cuts out the need to access an instance running on a remote server which may be useful in remote locations, meaning this can now be developed into an offline tool, it also means that node-red can get direct access to the phones hardware including GPS, Bluetooth or be an IOT gateway for sensors mounted on the tractor or implements.
UI for recording bale usage
UI for recording bales during harvest, bale count will be incremented by an Arduino or ESP32 on the baler.
Yes, it is.
I think this is going to be really useful for loads of projects. It’s sort of a pocket automation server could be interesting for linking devices like tag readers and weighing scales to the phone while creating logs.
Not really tried to make them work together, it’s more that I’ve tried achieving the same thing in 2 different ways to evaluate which is better for my use case.
Asset link is very promising as a general field tool but I’m leaning more towards the Node-Red option for the moment, for it’s ability to connect with external hardware/sensors. Also Asset Link is still in pre-Alpha and may be change significantly before actually being released. But since they are both web apps they may well end up living side by side, I guess some links between them would not be impossible.
I’m working a Quick Log Tab, It should work to create a basic log of any (/most?) log types. I figure it will be useful in the field for creating spontaneous logs on any asset, where the base fields and flags can be set with details in the notes, if a log needs more fields set then I can simply set the “needs review flag” and complete the log later with info posted in the notes section. Obviously for more common tasks I will have a more targeted Tab, but this is to cover scenarios not prepared for yet.
Just had a very brief look at the flow.
At first I got scared, and thought I had to upgrade
Those boxes, are they just a visual help for grouping nodes? Not seen that before. I see there’s a group menu item in node-red.
Link in/out is also new to me. Looks very useful in this case.
Is linking just a wireless (wifi ) connection between nodes?
The flow seemed userfriendly for general stuff indeed.
Nice work @Farmer-Ed
For my use when working with the crops, I think I would add some buttons to show more tailored data entry.
Or possibly buttons that prefill the flows you already made. That could work well too.
I’ve also worked on your csv-import flow the recent days.
It now picks fieldbee export csv file from my nextcloud, and formats it to suit my farmOS data.
Haven’t made the real import yet, but I’ll get there in the end.
I’ll have to decide on my workflow with FieldBee, and what to enter directly in farmOS.
A mix of those is propably what’s going to happen no matter what I decide
More or less, they also sort of lock the nodes together so they drag as a group, but they can still be edited individually,
Yea, these are kind of interesting and even work for connecting flows from different tabs, but I’m using them to keep it a bit more tidy looking.
Yea, lots of options, I’m keeping this one intentionally sort of vague in scope, for at least starting logs that I haven’t fully built flows for, but it will probably become the template for the more focused flows adding and/or removing fields as needed.
I’ve uploaded the latest version to GitHub which includes all of the logic to create a post, just needs some tidying up and maybe some sort of confirmation message.
Good stuff, I’ll be interested to have a look.
I do plan on revisiting my CSV flows too, I’ve learned a lot since I started with them and probably could refine them a lot, maybe you are already finding that yourself?
