additional baud rate for smart meters with infrared interface

[tqma1]

i want to use it with the Siemens TD-3511 smart meter which has an infrared interface which uses the following parameters: 300 baud, 7 bits, 1 stop bit and even parity can you please implement this?

Best regards, Thomas

Added in release that will be release any minute now. No guarantees it works with your setup though, not heard of any that use it with IR. But I see it uses IEC62056-21, so there is a possibility

@tqma1 It will be interesting to know if the firmware works on an optical interface - please get back and give us an update!

Thanks for your quick response and adapting!Until now I did not get it to work, but i do not unterstand why.An other solution is working:AMIS Lesermitterbaur.atThe code can be found at the end of the page.Maybe there is a need for this smartmeter to use also the rx from the infrared adapter?Best regards,Thomas Am 07.12.2022 um 12:30 schrieb ArnieO @.***>: @tqma1 It will be interesting to know if the firmware works on an optical interface - please get back and give us an update!

A quick skim through the source code, I see some serial.write, so it may need to request the data from the meter

i have found it in the description from the smart meter - there is the need of a request telegram And with this request telegram you can switch to an higher baud rate (19200)

So it will not work with my smart meter but great work from you!

That is right. This firmware will (currently) only work on meters configured for "Data push".
