Standards? You want standards? We have loads of those... Or why I can't control my heating yet

After I lashed out on the RFLink stuff mentioned here, I was thinking about other things it could be used for. And then I realised that we have a wireless heating thermostat! There's a box we can move around in the living areas, and a receiver/relay that turns on the heating when the thermostat calls for heat. Surely this would be a great opportunity for controlling the heating more closely, and even using in-room individual thermometers and RF-controlled radiator valves to deliver heat where we need it. Excellent!

OK. It appears that RFLink can communicate with Drayton wireless devices... Oh, mine's a Honeywell... ah, I think you'll find that that's a 868MHz device sir, I'm afraid you'll need a different RFLink gateway for that! Not to mention that there's an undocumented protocol between sensor and receiver. Bugger.

Nice idea though. I might revisit this sometime. There are some interesting RF controlled TRVs... e.g.
Smartwares SH5-TDR-A / SHS 5300 Heating Controller / Radiator Valve (Send + Receive) which is compatible with the RFLink.

Replacing Coffee Machine Pump (Dualit Espressivo)

Image
My 5 year old Dualit Espressivo broke on Saturday - disaster!! I was in the throes of making a coffee when the pump stopped, so no steamed microfoamed milk... Off with the back, check of voltages etc., taking extreme care because 240V + H2O is a Bad Thing. I located what seemed to be the pump, and there were volts on the terminals. Hmm. It’s an Ulka EP5FM according to the label. Google... Many people offering to sell me one, but the guys at ulka-ceme.co.uk aka Scintilla Pumps are the UK distributors. They sell a whole range of this type of pump, and the documentation shows that the crucial points are voltage/power, pressure (15 bar) and duty cycle (2m on/1m off). I can buy one online but I call them... they’re about 15 miles away, and are happy to sell me a replacement. We reckon it’s worth a lunch trip, so bowl over and it’s only £16 direct, vs £19.60 mail order. Done. The expensive part was lunch - £50!! Planning to skip dinner though... New pump fitted - looks like the old

Multiple SHT30 sensors on a single I2C bus with Sonoff-Tasmota

Image
I have a hankering to measure the input and output temperatures of my condensing boiler, in order to determine if it's likely to be actually condensing at any time. I have lots of SHT30 sensors, which attach handily to NodeMCU units. However, running 2 separate rigs, one each for input and output, means that temperature measurements will not be synchronised, which doesn't account for the action of the boiler and its heat output rate of change. It appears that the SHT30 has two I2C addresses (0x44 and 0x45), which are available on the Wemos D1 knock-offs that I have. So I started out by modifying one to use a different bus from the standard one - this is easily done by bridging a link with solder. I then used 2 NodeMCUs running together to check that the newly addressed device is actually detected and works. It does. Pair of NodeMCU/SHT30 setups in action Close-up of SHT30 devices -RH(44) has soldered address link (circled) So, let's see what we can do, eh? I

NodeMCU + Tasmota code + SHT30

Image
That was cool. Let's try something a bit "easier" - a NodeMCU module, which is easy to connect and upload to, in conjunction with a new sensor, the SHT30 that does humidity and temperature over an I2C interface. This is prompted by this article , which doesn't really say how to do any of this... Obligatory not very illustrative pic - bits are labelled pretty much! Oh yeah, had to solder the header pins onto the SHT30 - piece of cake now :-p. Compiled the latest Tasmota code (using the ESP 2.4.0 API + libs, which significantly improves the WiFi performance) in the Arduino IDE, it's already uploaded while I've been writing this. Gosh. And that was probably a bit rash! Re-compiled and uploaded, now I've edited the user_config.h file to include my Wifi details and a few other useful things. I'm hoping the code uses mDNS, because that's really handy. Hmm, that didn't seem to work - using the Serial Monitor indicates it's still us
