So you have your sparkly new Raspberry Pi and the first thing you need to do is remotely access it from the PC… and so you install TIGHTVNC… and put that on the PC and they talk to each other and…. no clipboard… This link got me out of a…

Pi PHP and CRON
Boy am I in it over my head (for now). my new Raspberry Pi turned up – very nice – formatted a 32Gig microSD, loaded Raspbian and after a couple of false starts I soon had a working (graphical worktop) operating system. I added FTP, VNC (so I don’t have…
DS18b20 and MQTT Graphs
As a background job, some of you will know I’ve been looking at averaging temperature readings as there can be a little variation when reading the DS18b20 for a variety of reasons, though nothing like the horrors I saw when using ESP201. On the ESP-10 with a 12” lead I’m…
ESP201 Performance
Maybe it’s just me.. I’ve been messing with the DS18B20 and the ESP-01 and on advice from a respondent in here wrote a quick averaging function and have been monitoring that all morning – lovely. No connection issues, nothing. So this afternoon I took my little ESP-01 development board (which…
Temperature variations
How useful is this MQTT-SPY turning out to be – I had no idea I had such temperature variations from my DS18B20 – ok it looks worse than it is due to the limited range of the graph but I really do need to do some averaging!! This is just…
Onion Omega
You (probably) saw it here first… I thought I’d seen it all in the ESP8266 but this is looking impressive already. Yes, that IS a complete WIFI controller with Linux and plenty of RAM in a matchbox. Early days, I should have one to test in a matter of weeks…
Easy MQTT Graphing
I’m quite excited this morning, had an email from Kamil Baczkowicz – could I please try the latest beta of MQTT-SPY – I’ve been encouraging him to add graphing for the MQTT input as even Node-Red doesn’t do this out of the box.. sure enough he’s cracked it. Here’s a…
The BLANKER is there for why?
In the MQTT software for the ESP8266 (ESP-01 etc), specifically the MAKE file, there is this line.. $(PYTHON) $(ESPTOOL) -p $(ESPPORT) write_flash 0x00000 firmware/0x00000.bin 0x3C000 $(BLANKER) 0x40000 firmware/0x40000.bin It’s pretty obvious what it does, it blows the two BIN files you’ve just created. By what I don’t understand is why…
MQTT SPY Graphing
If you’re using MQTT-Spy – you HAVE to check out the latest beta – I asked Kamil to introduce graphing and he’s made a start, so now straight from the PC desktop you can graph your MQTT – marvellous… check the latest BETA – http://kamilfb.github.io/mqtt-spy/
Domoticz
Ideas anyone? Installed Domoticz just to see how well it might work… needs an add-on for MQTT here https://github.com/sschimmel/DomoticzMQTT – grabbed that, put the files in nodejs\node_modules\domo and ran node server.js as per the recommendation.. and.. it threw an error “Cannot find module “mqtt” Update September 2015: MQTT is now…
Landing on two Feet
Sometimes I really do land on 2 feet. So the ESP/MQTT rig now appears bulletproof and in a timely fashion the Raspberry Pi appears just in the nick of time. All I need is an easy to use Mosquitto/Node-Red setup and …. what should appear but a link to this…
ESP12 and More Pins
I’m just about to have a go at one of the larger boards – the ESP12 (or 201)… so can someone save me (and others) re-inventing the wheel. Here’s what I do to initialise an ESP-01 port bit GPIO0 as an output. Firstly the setup.. // For GPIO2 just change…
Rubbish plug-ins
Another rubbish spam plug-in – apologies to anyone who’s been trying to comment this morning – I really do not understand some of the people that give stars to WordPress plug-ins. I used an anti-spam system that got high ratings – and it would not let people comment – when…
ESP8266 and MQTT Exciting Times
I don’t want to jump in prematurely here but those of you who have been reading the blog will know that I’ve had no end of problems with the MQTT stand-alone software on the ESP8266, but as each problem has emerged, the author (Minh Tuan) has been keeping in touch…
Raspberry Pi 2 Fast Enough?
The Raspberry Pi is a nice, cheap little computer but for me it has never been fast enough – I’m not interested in making another media server (I have a DISKSTATION which does that just fine) but as I’ve recently been working with MQTT in my home control setup, I…
MQTT SPY
There’s a new MQTT-SPY out – here http://kamilfb.github.io/mqtt-spy/ This program has been invaluable to me throughout all the time I’ve been testing and learning about MQTT. It sits on my desk running constantly and never falls over. Properly set up it can send timed messages out and coming soon –…
Memory use ESP8266
Can someone explain this to me.. I’m using the ECLIPSE environment in a PC and only starting to get to grips with the MAKE files – I really still don’t understand most of what’s in there. I’m looking at the MQTT installation which is one of the easier ones (I…
