This entry is about ThinkStudio (thingstud.io), Web Sockets and Mosquitto in my quest for ESP nirvana.
So TODAY I was alerted to an early version of a new service which I think you might like… so check out http://www.thingstud.io/
Clarification: This is ALPHA software but already, provided they keep at it I think this has the potential to replace the rather slow-moving NETIO app which provides a nice user interface for IOT.
This software uses MQTT which is right up my street.
Well, always one for a challenge, I went to the site, set up an account and…. nothing – not a thing. I put in my MOSQUITTO (MQTT) credentials and got absolutely no-where apart from having a nice pretty interface. They have a nice pop up live help (pretty amazing for an alpha product) and before long I was happily chatting away to Michael Karliner. It turns out that the product needs MQTT to have Websocket support which my Mosquitto on the Raspberry Pi does not. I’ve been putting it off because every explanation I’ve seen up to now involves compilers and all sorts of horrible things.
I was pointed to this link… blog.thingstud.io which Michale had just completed - and in there is an article about installing Mosquitto with websockets. I was in one of those “devil may care” moods and so figured there was no reason why this could no upgrade my existing Mosquitto.
So I did – I followed the instructions from the start right up to but not including the bit about installing Node-Red as I’ve already done that.
WELL BLOW ME!!! it worked. Well… not quite. It over-wrote my mosquitto.conf file with a virgin one so now my security was bust and my local boards could not talk to anyone.
I opened the virgin mosquitto.conf which had everything commented out and added these lines as per the blog
So now I could run a websocket on port 9001 (I tested that by redirecting the port on my external address then trying http://www.hivemq.com/demos/websocket-client/ – worked a treat)
That allowed the websockets to work – on port 9001. But… my normal port would not work any more – 1883.. so I added this.
That got both pipes listening – all that was needed was to restore my user access.
And Bob’s your uncle – the latest Mosquitto (which is just excellent) and now websockets.. which means I can write my own web pages to access MQTT if I want to!!! And no doubt I will – but if ThingStud.io works out – I might not have to. Ensure you are registered to get updates in here or follow my usual Twitter and Facebook accounts to make sure you don’t miss out – I have a hunch about this one.
Update: Oh I found another link with instructions for installing websockets – and a little info on the mosquitto.conf file…
