Eastron SDM630 energy meter - new sensor

[gtortone]

Hi,
integration of a new sensor: Eastron SDM630 three-phase power meter.

Regards,
Gennaro

Thnx.

I'm in the middle of a release update which will use your changes to xsns_23_sdm120.ino. This has just been released in the development branch.

Hi, I added also a Python implementation of HTTP server for OTA updates

Requirements:
   - Python3
   - pip install netifaces flask 

Instructions:
    Copy Sonoff-Tasmota firmware binary files in 'fw' directory. 
    A set of prebuilt files can be downloaded by Sonoff-Tasmota release page:
        https://github.com/arendst/Sonoff-Tasmota/releases

    Configure your Sonoff-Tasmota device with your fw-server URL:
        Firmware Upgrade -> Upgrade by web server
            http://<ip_address>:5000/sonoff-minimal.bin

Usage:
   ./fw-server.py -d <net_iface>   (default: eth0)

Example:
    ./fw-server.py -d wlan0

Grrrrrrrrrrrrrr. You are blowing my release Travis compiles.....

[arendst]

Restarting the build just now. Give 15 minutes for the binaries to compile.....

[gtortone]

Sorry,
I will wait for your release !!

[gtortone]

@arendst please let me know what do you think about fw-server... I know it should be a separated PR !

[arendst]

It's a great idea and a good alternative for an apache server et al.

I play with it and let you know my findings (when I'm at rest after finishing the release...)

[arendst]

Release finished. It's all yours again...

Hi, keep in mind that rs485 is a bus, and
frame[0] = 0x01; // default SDM630 Modbus address
works only for one device on address 1.
I plan to have 3 SDM630 and 2 SDM230 (house, apartment, total, solar plant and what we use together) al sitting on the same RS485 cable. Would be nice to query them with one tasmota device, not 5 ;-)

A config option where i can set up SDM630 / 230 addresses would be needed, also some sort of "autodetetion" (120,230,530,630 on address) would be something to consider for version 2.x

btw, nice job. Will free me a raspi that is doing the rs485 job now! thanks a lot!

[gtortone]

@MatzeJoerling Yes, RS485 is a bus and SDM120 sensor for Sonoff-Tasmota is a first release that could grow in next future (I hope). I'm starting to think how to implement the ID setting of a 'set' of SDM sensors and my first idea is by MQTT messages (or serial / web console)...

[arendst]

Released. I still need time to investigate the fw-server though so that has to wait.

It's in my local repository so I suggest to close this PR.

[gtortone]

Thanks a lot !
I close this PR.

@gtortone I tried your webserver and I like it's simplicity!!!

On Linux it works great and so much easier than setting up an apache server et al.
Still testing on windows ...

[gtortone]

@arendst Thanks ! With Flask framework an HTTP file server in ~30 Python lines of code is very impressive (and simple) !

[arendst]

Still struggling with windows...

I manage to find my interface device name which also returns the correct IP address:

but executing the fw-server always returns this:

fw-server.py: error: no such option: -I

Beats me where the option -I comes from

[gtortone]

Hi,
see here: #2759

[gtortone]

btw I suppose you should try with:

.\fw-server.py --dev '{AC6EA539-40B4-4921-A3BD-E081354D06CC}'

[arendst]

No that returns:

.\fw-server.py --dev '{AC6EA539-40B4-4921-A3BD-E081354D06CC}'
E: network interface error - list index out of range

Without the quotes it gets past the network interface check but fails down the line.
