Same here… need to buy a license… but I can’t get Fully Kiosk to always stay asleep and stop the screen saver kicking in a couple of times a day… no bit deal, just a quick swipe up.
Will keep poking about.
If anyone has followed my various attempts to get this data reliably, I have created a Node-Red node that will pull the Agile pricing data in and give you various size minimum price blocks. Feed this into MQTT and EmonCMS will pick it up.
Very rough for now but works. Not exhaustively tested mind you…
Documentation is minimal right now 
.
Install as any other node but use
npm install https://github.com/borpin/node-red-contrib-octopus.git
You might need to use --save.
I’m using NR within Home Assistant - it is just too easy not to - I can add this command within the config from HA.

Hi Brian,
I would like to give this a try, but in reponse to
npm install https://github.com/borpin/node-red-contrib-octopus.git
I get this error log, Sorry, do you know ehere i am going wrong?
Best Regards

Short answer is no 
. I have only tried to install it into a Node-Red inside Home Assistant. I presume this is outside that.
Did you try the --save?
You might be better asking on the Node-Red forum. If you @ me in I’ll see the question and if there is anything I need to do I can try and sort that out.
Hi Brian,
Thanks for the quick reply! I did try the --save, and also with sudo, which resulted in a permissions error oddly enough.
I have just installed node red on my emonpi so its a bare install, I think i will have quick go with HA if thats the known working route!
Kind Regards
James
If you have HA installed somewhere, then it is definitely the best route assuming you are either using HASSIO or the Supervised version. You can add NR in as an add-on as well as InfluxDB and Grafana. All this can then get automatically backed up.
I am becoming more and more impressed with HA as a full system - all the bits just seem to work seamlessly together.
Hi Brian,
I have HA and the node red add on installed and working. Next daft question?
There do i runn your install command from? If i run from a ssh shell i get
npm WARN npm npm does not support Node.js v10.15.2
npm WARN npm You should probably upgrade to a newer version of node as we
npm WARN npm can’t make any promises that npm will work with this version.
npm WARN npm Supported releases of Node.js are the latest release of 4, 6, 7, 8, 9.

So it evidently doesnt know where to put everything, and its not apearing as a node.
“I can add this command within the config from HA.” Sorry for being daft, I have no experience of HA or Node red, I can i run this from the GUI somewhere?
Best Regards
James
Found it 
Sorry for the daft question.
Best regards
James
I tell folk there is no such thing
I use as below
You can also load a specific branch
One issue I have found is that as I prevent the node running too often, this is a pain when testing! I need to add a specific inject message to force update

Good Morning Brian,
I have been playing with this sucessfully for a while, but yesterday its seems to have broken.
Node red doesnt seem to like you package anymore, did you change something? Is your build still ok?

Hi James, how are you installing it?
Just restarted my Home Assistant add-on and it loads the package no problem. Has anything else changed?
I did update the version and added an output for use with InfluxDB a week ago.

Hi Brian,
Thankyou, I swapped
‘npm install GitHub - borpin/node-red-contrib-octopus: Octopus Node-Red node --save’
for
- 'git+https://github.com/borpin/node-red-contrib-octopus.git'
and this fixed it!
Great work on this, its very usefull, thank you for sharing!
Best Regards

I have created a feed that takes the Agile costs and loads them into Emoncms (input). I run a python script every 30 minutes (+1) which loads the value.
This is great for seeing the costs now but I wanted to feed in the costs for the future ( aka the Octopus Agile app).
The idea is to combine these projected costs along with other areas as per the initial request for help.
Is there a way of directly loading the feed with future values rather then relying on the input? I assume a feed takes the current input value and provides a timestamp. SO is there a method I could insert directly into the feed which would then complete what I need - maybe there is an API call I could send data to feed rather than input?
thanking you in advance - Andy B
Apologies everyone. I have found the details for feed API so will follow that.
Having tried in vain to create something myself in NR, just discovered this very nice contribution, thank you @borpin
I’m trying to get the live price for Octopus’ Cosy product which i gather is just a change to the Product & Tarriff code in request URL. Is there any way to modify this either in the Nodered GUI or a config file somewhere? As you can probably tell my engineering skills are somewhat limited!
I have the raw Cosy data coming from Octopus OK thanks to @Timbones, just need to isolate the current price for which this custom node appears to handle all the complexity.
BASE_URL="https://api.octopus.energy"
PRODUCT_CODE="COSY-22-12-08"
TARIFF_CODE="E-1R-$PRODUCT_CODE-J"
TARIFF_URL="$BASE_URL/v1/products/$PRODUCT_CODE/electricity-tariffs/$TARIFF_CODE/standard-unit-rates/"'
Many thanks
Currently no. When I did that, there was just one Tariff!
Thank you! I am obviosuly v. late to the party and just discovered this. Assuming easy enough to mqtt back to emoncms, it’s just what i needed. I’ll have a tinker
If you want a Node-RED solution try this (you will need to modify the URL used)
