Who would have believed this is possible! Nick and Peter Hoddie had a chat at OpenJSWorld22 and Peter has started a project to run Node Red flows on ESP8266 and ESP32 using Javascript and Moddable. I purchased Peters book on Kindle and over the last few days, setup the tool chain and did some of the…

[image] mtoko: setup the tool chain and did some of the examples Hey @mtoko , Thanks for sharing this!!! Have been hoping for many years that something like this would ever appear... Can you give an idea of the amount of work/time to get started with this? Bart

Hi Bart, it took me some time, but I was learning some new stuff along the way. The Getting Started guide on the Moddable Github page is the place to start. I followed these instructions and got everything to work with the simulator and an ESP8266. This is to understand the Moddable and Javascript o…

I'm really having a lot of trouble believing this!!! :slight_smile: For a doubting Thomas such as myself - can you post some screenshots/little snippets of code to convince me that this isn't just an early April Fool! :slight_smile:

I've had a look at the links now and I can maybe believe it now :slight_smile: I was think no-way can we edit/run flows on such devices! And , of course, they can't run a live editor but it seems they can read and execute a flow sequence in a flows.json file Very clever :slight_smile:

[image] cymplecy: they can't run a live editor but it seems they can read and execute a flow sequence in a flows.json file Hey Simon, Didn't have a chance yet to read about it. Do you mean that you run the Node-RED flow editor e.g. on a Raspberry, and that you generate (e.g. for a limited s…

You export the flow as normal and then copy it into a Node.js folder that is downloaded to the ESP This is the extract from the instructions which suggests that the debug can be used and the results display in the ESP debugger, but I don't understand this and have not tried it yet :grinning: Debug …

Ah ok, thanks for the clarification!! So they show currently everything in the xsbug window. It is getting a bit more clear now: [image] Run a normal Node-RED runtime, e.g. on a Raspberry. Create a flow with a limited set of core nodes (supported by Moddable). Export that flow to a json file. U…

[image] mtoko: Remember this is all very new Had a quick look at the commit history of node-red-mcu , which tells me that the first commit was 5 days ago. A Node-RED runtime for mcu in one single JS file. Very impressive...

I will make an attempt to give this a try this week. It should be fun and very interesting.

That diagram is how I understand it. Remember this is all very new and is not the finished article. I think it would be good for members of the community to apply their Node Red experience and assist with the development
