I use a self designed PCB with a ESP07 module. TX is connected to GPIO1, RX to GPIO3 and GPIO4 is used to enable the RS485-Transmitter.

Hi,

Using a WiFi Adapter, but values are empty.

Dump mode shows values .

Thanks.

these dump values marked with > are requests send to your meter and there is NO response from the meter.
check LEDs on your RS485 adapter RX and TX LEDs must blink on successful communication.

[anticharm01]

Hmm, the clear led flashes.

[gemu2015]

The above script is for a MODBUS meter. This optical head does not seem to be ment for MODBUS ?

[anticharm01]

Ahhh, uhhhm.

Docu says "(SML, OBIS-) signal"...

Good point.

[anticharm01]

This is beyond my capabilities. I have no idea how to get a single bit out of that meter via infrared.

The manual says

"It corresponds to the communication standard IR (near infrared) and RS485. IR meets the requirements of the protocol EN62056(IEC1107), and the communication RS485 uses the protocol MODBUS."

What is "EN62056", is it OBIS?

How do i get this meter to send something or how to get to know it is sending?

thanks.

[gemu2015]

for MODBUS which i would prefer you need an RS485 to TTL Adapter, then connect the meter via wires and use the above script

[anticharm01]

yeah, sigh.

Thought it was such a simple thing. The meter has infrared, the small reader has an ESP with WIFI on board.

 flash Tasmota - add to Home assistant - everybody happy. FAILED.

Maybe I try to drop the led header and use the ESP to read directly from ModBus.

Thanks

[anticharm01]

Another thing, that came in my mind... maybe infrared has to be enabled somehow. Manual says nothing. There is some software, somewhere... and I need... a cable. Damn.

[gemu2015]

if you get to know the exact protocol of the IR interface you could also use this with your IR head, but i could not find any further info about this meter.

[anticharm01]

I'm trying to find the original software. It's not on the homepage but I saw a link in one of the forums.

Have another approach with a Hi-Flying Protoss PW11. Ordered it minutes ago. :)

Thanks

[anticharm01]

Found something :)

[anticharm01]

Could not connect via IR. Tried IR to USB head, too.

Finally ended with a PW11-H ModBus to TCP.

Working fine.
