Roomnodes

Having worked well for 5 years it is time for a network service.

One of my jeenodes has suffered somewhat being outside in a plastic bag.  Known as compost node (and in some months as "are the pipes too cold" node) it has now stopped working.  My normal first approach is to reprogram the main chip.

However that involves decomissioning the room node which has a socket which has been used many times.

I would like to get hold of 1) a roomnode and 2) a cable to connect - since I believe all the jeenodes apart from roomnode cannot 

be made to work with the serial cable even if you put a connector on.

On the sales board I see there is a cable available but not a roomnode.  Is there any way I can get one - maybe even pay someone for a second

hand one?

Hiya Kim,Like many of us in

Hiya Kim,

Like many of us in here we only pop on infrequently these days as the system is so stable (thank you) 

Are you still in need of a roomnode? I have some spares (Why buy 1 when you can by 10 ? :) )

Hi MarkThanks for replying -

Hi Mark

Thanks for replying - yes I would be interested in two if possible.  Email is kim@btinternet.com

I agree about the reliability.

Regards

Sorted...

......thanks to Mark for sending me stuff.  I am now progressing well with repairing my system, discovering that the reason one wasn't working was simply because the RFM12 module had changed frequency to 433mhz.

Looking at all the stuff on Wemos D1 mini and IOT dashboards, I am realising just how far ahead Brett's xap stuff was.  I still can't

find something free like Xlively which will give me flexible graphs easily.

So now I am wondering if I can easily integrate the esp8266 toys but make use of the xap protocol and xlively platform.  Probably a step too far for me - but ideas welcome.  I see brett did do some esp8266 stuff a while back.

Regards

Hey Kim thanks - Its

Hey Kim thanks - Its suprising that 5yrs has passed and people are starting to catch up with what we have achived here using xAP.  There is so much that was ahead of its time and in some cases still ahead.

Any of the roomnodes you can communicate with using serial, its just a matter of what firmware you have flashed down on the AVR.   I'm pretty sure Derek could rustle up a pcb.

On the ESP front I'm trying to recall if I managed to get xAP running on these.  From memory I didn'y using LUA as UDP broadcast was not supported and I had to use an MQTT bridge.  This did work pretty well.

I believe the LUA library has advanced somewhat and the ESP chips have more memory so it might be possible to run a fully native LUA/XAP stack on them.  Most certainly if you drop back to C setting up an xAP stack would work without any issue.  I've got a couple of those unit here so I'll give it a bash.

Interesting...

.....  I think before there was not enough memory.  Now you can get a Wemos D1 mini for £2.35 delivered (albeit with a delay) and 4M memory.  

I have always been right on the margin with transmitting distance for the jeenodes from the compost bin (!) - and if I could work out how to plug a basenode into the usb of a wemos then I could use it to put xap messages on my home network via wifi.  I don't know really how it works, but I have two liveboxes - one records the jeenode stuff and puts it on the network and another picks it up and publishes it to xlively - which platform still has the ability to produce different length graphs (selected by the user) which I can't find elsewhere (free at least).

868mhz goes through granite walls better than wifi 2.4ghz (and certainly better than 5ghz wifi).

All input most welcome.
