LED strip too dim to power SAD light

 

Cheap LED strips arrived today but too dim to illuminate the small panel brilliantly enough. 

 

 

Will order the ones recommended now

https://www.ebay.ie/.../DIY-LED-U-HOME-High.../182601655119

 

The CRI of 90 or above is the important bit

Though, while I'm waiting 4+ weeks for those, I could try using both 2M strips behind the panel rather than illuminating from the side.

Nope it doesn't diffuse the lights well enough.

The large panel might though? Well it diffuses OK but even with two strips and them all facing the panel I doubt if it would have the brilliance needed to provide a strong daylight experience. But I could try tomorrow.

 

 

 

Checked if EPEVER Tracer4215BN charge controller still works. Conclusion: Maybe

 All looks good. 

https://www.hinergy.net/product/solar-charge-controller-4/

 

 

At start (14:11) battery 11.95v and panel 13.97v:

And later (16:03) in the day, 11.95v @ 120mA battery, 13.61v panel

So no increase in battery voltage even though EPEVER green LEDs are both on.

A bit later still (17:33) 11.89v @ 120mA battery, 13.19v panel

So battery voltage has actually gone down! Due to powering EPEVER unit?

https://www.solarpanelamerica.com/wp-content/uploads/2018/02/EP-Solar-Tracer-4215BN-Installation-and-operation-manual.pdf

Which states on page 20:  <=60mA @ 12v

 So more testing needed!

 

Got broken LED screens for SAD lights

I had seen a great Youtube video on how to make cheap SAD lights.'

So did the same :)

Might be able to use existing PSU for large screen.

Googled "LED strip JLD320B1235"

https://www.electromix.co.uk/led-strips/3647-jld320b1235-078cs-c-led-strip-el6820-wj2.html

https://www.aliexpress.com/i/4001111181238.html?spm=2114.12057483.0.0.6f3a7f015dsMaO
So 3V each element is that 3V x 22 x 2W or 33V x 2 or 66V ?
Best try 3v battery first :)

Product Description
Backlight strip production information
1.Consistent with the original, Brand New, no need to modify it, easy to install
2.Long operating life, typically lasting over 100,000 hours
3.Brightness is consistent with the original, brightness up to 700 nits
4.Product length: 575 mm( length) * 10mm (width) * 1.0 mm (height) , 11 LED Lamps
5.Voltage: 0-94V, Single lamp voltage is 3V

(19:34) Excellent so how do I provide 66V at (2W a lamp) so 44W is 750mA.


(20:51) Can I get 90V at 200W from the old PSU?

file:///home/kilnageer/Documents/SmartHomes/SAD%20Light%20Panels/map3249_datasheet.pdf

The MAP3249 (U2) takes VIN pin 16 (12v) and EN pin 5 (driven by BKL_ON/OFF which is pin 5 of CN4) and is active high.
It also takes PWM pin 14 (6v max, TTL levels, 100 to 2KHz) (driven by PWM_DIM which is pin 7 of CN4) and ADIM pin 3 (driven by V_ADIM which is held at 2.6v by voltage divider from V_REG (which is VLDO pin 1 of U2)

GATE pin 13 becomes GATE_CON and controls Vled
CS pin 12 becomes CS_CON and also controls Vled

CN6 only Vled pin 1 and CH_4 pin 7 (55v max) are used by wired connection lead. Is this 24v to the LEDs?

Will try it tomorrow with a NodeMCU providing the PWM will then upgrade my Solar Pump NodeMCU code so if it doesn't get a command in 10 mins it takes control and goes into safety mode!

Kamstrup OMNIPOWER investigations

Well I built the kit I had bought using PayPal to his e-mail address for 21 euros.

https://wiki.hal9k.dk/projects/kamstrup

Google Translate is your friend when translating from the Danish :)

All went well though as he suggested you need to drill the holes for the LEDs and the magnets.

I based my design on an ESP8266 NodeMCU v3 LoLin board I had lying around (select Arduino board: "NodeMCU 1.0 (ESP-12E Module)" from library ESP8266 by ESP8266 Community version 2.7.4 using preferences:

       http://arduino.esp8266.com/stable/package_esp8266com_index.json

After much unwarranted trepidation on my part everything worked first time! And using his code the device successfully requested 6 registers but got all zeros back. Obviously, I was hoping for useful usage data like in his post:

But instead I got:

11:21:15.527 
11:21:15.527 Kamstrup OMNIPOWER Meter Reader: v1.0 Thurs 10th Dec 2020 11:13

11:21:25.933 53: 63,16,0,53,51,4,0,0,0,0,0,105,46, 13

 

So what I found was that my meter worked differently to his. So I polled all 64K registers to find out which ones would respond. I found 50 that responded:

But none of these appeared to change which would indicate they held a power reading.

Though some did match with meter serial number etc. But all static data.

Though, in hindsight there is one, 1047, which appears to have date/time. 

11:09:57.018 1047: 63,16,4,23,53,8,0,2,2,55,9,11,8,12,20,76,157, 17

11:10:11.664 1126: (63,16),(4,23),(8.0.2.2),sec,min,hour,day,month,year,(76,157)

So "11:09:55 8th Dec 2020". I now also know that 0.8.0.2.2 is the OBIS code for the RTC.

I send e-mail toi ESB networks asking for a:

Consumer communication channel (CCC) module

https://www.kamstrup.com/en-en/electricity-solutions/smart-electricity-meters/single-phase-meter

https://products.kamstrup.com/documents/5162b47e9a3ff.pdf

https://github.com/emontnemery/domoticz_kamstrup_mqtt

https://wiki.hal9k.dk/projects/kamstrup

Bought the kit from Facebook / PayPal for 21 euros.

Smart Electricity meter installed by ESB Networks this morning

I had requested a night meter so that I could charge my batteries cheaply at night and draw power fro the during the day. However, after any e-mails between myself and ESP Networks, Community Power and CRU (https://www.cru.ie/home/smart-meters/) a fella just turned up out of the blue.

 

Sadly, while in Germany I could insert a module to allow consumer monitoring the ESB have security tagged that slot.

See page 10 of:

https://products.kamstrup.com/documents/5162b47e9a3ff.pdf

"In OMNIPOWER® single-phase meter, it is possible to mount a CCC module. The module can be used for communication and data exchange with smart home products such as energy displays and external relays. The CCC module is mounted without using tools or breaking the seal of the meter. The mounting may be done by e.g. the consumer himself."

  However, there's an IR window that should allow serial comms to the unit. https://wiki.hal9k.dk/projects/kamstrup

 

 I've bought one of these kits and should be able to attached magnetically to the smart meter.

 

And read basic usage data from a NodeMCU and post to MQTT

Tuya ZigBee TRVs proving tricky to control.

The first three I bought work fine on my Raspberry Pi Zigbee2MQTT set-up but the second three need to be woken up before they will hear a command.

But I've sniffed the comms over Wireshark when using their app so I should be able to crack it.

 

This command worked!

Oil tank sensor

Installed an oil tank level monitor in Tola Park yesterday.

Based on a HC-SR04 ultrasonic sensor and an ESP8266 NodeMCU module and code from:

https://www.instructables.com/id/Distance-Measurement-Using-HC-SR04-Via-NodeMCU/

It publishes to MQTT which can then be displayed as a graph using Node-Red
