Hi , i made my own optic probe , i can read all data with an arduino. Also i prepared a video about how it works. Here is the description video :

hi , last week i could do it and read a meter; but for set clock and date i dont know what commend is for it
i can read act5000 and jam200
thanks -

Hi , which circuit you use in order to read data from meter ? my circuit or anohter , just i wonder.
Do u use any mcu to send data or usb-ttl? -

at the first , i only used two led tx , rx and when i get answer i made circuit above that diogoc put it,i only used left part and connected to usb to ttl , and so get obis codes and now i m analyzing obis codes , im trying to set clock the meter but i have not done yet. could you do it? -
Sorry , i have not try yet.

hi, i'm working on optical probe too.
as far as i know, to change anything in power meter - date and time too - you must enter a password, which isn't easy to get - almost impossible ;) there are different levels of access to power meters - without password we can ony read some values - if your power supplier grant you to read them - some power meters has optical interface disabled.

I have almost working this communication.
Comercial optical probes like this are expensive:
Optical probeSo I build a optical probe based on this schematic
Communication protocol tested on my meter:
Baudrate: 300 bps, 7 bits, parity even, 1 stop bit Send: /?!<CR><LF> (wake-up and sign-on) Receive: /XXX5YYYYY<CR><LF> (XXX is the manufacturer ID; YYYYY is the meter ID; 5 is the new baudrate = 9600 bps) Send: <ACK>050<CR><LF> (send ack; reading mode) Baudrate: 9600 bps, 7 bits, parity even, 1 stop bit Received: C.1(201236731.0(01:39 25-08-18) 1.8.1(0004398506*Wh) 1.8.2(0000000000*Wh) 1.8.3(0008198809*Wh) 1.8.4(0000000000*Wh) 1.8.5(0000000000*Wh) 1.8(0012597315*Wh) 2.8(0000000000*Wh) ! DNow I only have to parse the values of tarif 1 (1.8.1), tarif 3 (1.8.3), and total (1.8)
