Wired up USB to serial converter to Stats Hub..

But need to be able to view the schematic files first!

Such as :

and

Installed RadBot..

Well I unscrewed the Radbot case and added two AA batteries..


Saw red LED which was encouraging then swapped my Lets Talk Solar RF TRV for Radbot...


Then expected to hear motor or something but silence..

So I switched to The Stats Hub to see if can hear the Radbot. I installed two AAA batteries and a red LED re-reassuringly flashes. But how to talk to it.


Should be an Arduino like device so got Arduino IDE installed on my Fedora 25 laptop (see https://www.arduino.cc/en/Guide/Linux) and checked it was working using a shrimp breadboard..

[kilnageer@localhost arduino-1.8.1]$ pwd
/home/kilnageer/Downloads/arduino-1.8.1
[kilnageer@localhost arduino-1.8.1]$ sudo ./arduino

Selected 101 board and port /dev/ttyS0 and downloaded the flash demo program..


That works so need to wire up the USB to serial cable to the Stats Hub..job for tomorrow evening :)

Got OpenTRV valve and data logger today..

Got OpenTRV valve and data logger today..
Next step it getting it to control the in my bedroom in Tola Park and see if it talks to the data logger over RF.

Heard about Nick Rosen and http://www.off-grid.net

I found Nick Rosen mentioned on the web and then joined the http://www.off-grid.net/ website.

I will start chatting with members on it to keep me enthused with my own projects. I also posted "Aim to go off-grid by 2020" to that site: http://www.off-grid.net/aim-go-off-grid-2020/

By the way, I will post details of my solar water system (installed in Shannon, Clare in Feb'16) shortly. Here's a taster...

I find it excellent at providing a cylinder of hot water for showering and washing dishes. Details soon especially of the control system :)

My aim is to test bed technologies in Shannon (where I live and can keep an eye on them) and then deploy them (debugged!) to Mayo.

Bought components to deploy my 1KW wind turbine. The idea being:




1) 60A cable: "800W 60A 60 AMP 8 AWG Car Amplifier Fuse Wiring Kit Audio Sound Power Cable Wire" from ebay:





Which features:
Power cable’s length: 4.8 m
    Ground cable’s length: 0.5 m
    RCA – RCA cable’s length: 4.4 m
    Remote cable length: 5 m
    Binding tape’s length: 5 cm
    Fuse holder’s size: 9 x 4.2 x 2.5 cm
    Fuse maximum current: 60 AMP

    Power cable x 1
    Ground cable x 1
    Remote cable x 1
    RCA – RCA cable x 1
    Fuse holder x 1
    Prong terminal x 4
    Binding tape x 4


2) Isolation box: IP65 Mini Garage Consumer Unit Fuse Box C/W 100A Isolator Switch + 6A + 32A MCBs

Which features:
IP65 ABS ENCLOSURE, POLYCARB FLAP
HINGED FRONT COVER
100 Amp Mains Isolator Switch 1 x 6A + 1 X 32A. MCB as Standard
DIMESIONS 229mm(h) x 140mm(w) x 105mm(d)





3) 60A in-line fuse: In Line Maxi waterproof Blade Fuse Holder 60a 60 amp fuseholder car boat van this fuse holder accepts MAXI FUSES ( NOT THE STANDARD ( large fuses  30mm x35mm ) the fuse holder is made up with 8 gauge red wire that can be cut to the desired length, the wire length is 250mm




4) 1,2KW dump load: 10x Reprap 12v 40W Ceramic Cartridge Heater (3D Printer, Prusa, Mendel): Current:12v, Power: 40w,Core: ceramic, Diameter: 6mm, Length: 23mm, Lead Wire length: 100mm (30 pieces)






What I intend to do is create a number of increasing 45v/48v loads: 120W (3 in series - 3 pieces), 360W (3 in series and x3 in parallel - 9 pieces) and 720W (3 in series and x6 in parallel - 18 pieces). So as the wind turbine spins-up and the current it generates increases then the load will switch from 120W (always on) to 480W (added 360W load) to a maximum of 1200W (all three loads active). This will allow the turbine to start-up in light winds as it doesn't have to drive the 1.2KW load straight away.

I intend to fix the barrel heaters to the inside of a double radiator where the corrugation is.




So that they heat the water in that radiator and the central heating pump takes it away around the house to the other radiators. (Here the CH burner is turned off).









Commisioned new 230 V AC immersion heater...
Replaced existing 230 V AC immersion heater. The idea being to use the wind turbine to drive a 48v 1KW immersion heater to constantly heat up the hot water cylinder. Then with the central heater turned on (but the burner turned off) have the CG pumps act as a reverse heater exchanger heating the burner loop and rad loop from the hot water cylinder. Normally, teh burner would be active heating the water in the hot water tank loop (and radiators if the valve is open).
