OPEN DTU for Hoymiles ZERO Export with Shelly EM and Shelly Smart Plug

[Stratis63b]

The reason i ma writing to the Group is to see if you have tested the product with Shelly EM and smart plug
At the moment Hoymiles proposes DTU PRO and Chint 666 3ct , a very expensive solution for Balcony Solar modules,
So OPEN DTU solves the DTU PRO issue but still we need th Chint Smart meter .
Sorry for my English but my German is worst
Hallo Lukas
und herzlichen Glückwunsch zu Ihrem OPEN-DTU-Projekt,
Der Grund, warum ich Ihnen schreibe, ist, um zu sehen, ob Sie das Produkt mit Shelly EM und Smart Plug getestet haben
Im Moment bietet Hoymiles DTU PRO und Chint 666 3ct an, eine sehr teure Lösung für Balkon-Solarmodule,
OPEn DTU löst also das DTU PRO-Problem, aber wir brauchen immer noch den Chint Smart Meter.
Sorry für mein Englisch, aber mein Deutsch ist am schlechtesten

Hallo Stratis,

ich habe bei mir openDTU mit Shelly 3EM und Shelly Plug ohne Probleme am laufen.
Als Nulleinspeisung Script benutze ich https://github.com/reserve85/HoymilesZeroExport/
Am Shelly Plug habe ich aber Tasmota installiert da man es besser Kalibrieren kann.

Der eingefügte Link funktioniert bei mir nicht. Könntest du da nochmal drauf schauen?

[mark82436]

habe es geändert

I guess you meant this https://github.com/reserve85/HoymilesZeroExport So you got Ahoy DTU or Open DTU and then you added this script, Cause the installation instructions are not very clear.

Hallo, würde auch gern mehr darüber Wissen (kleine Anleitung) vielen Dank

[bscholtes]

for a first setup I prepared a docker container with suitable ini setup and entrypoint for a simple docker run ...
with "--init" for SIGNAL handling and "--restart unless-stopped" for automatic restart to docker options

Dockerbuild:
FROM python
ADD HoymilesZeroExport.py .
ADD HoymilesZeroExport_Config.ini .
RUN pip install --upgrade pip && pip install requests
HEALTHCHECK --interval=60s --timeout=2s --start-period=45s CMD [ "$(tail -1 /log/log | awk -F':' '{print $$1 ":" $$2}')" = "$(date '+%Y-%m-%d %H:%M')" ] || sh -c 'kill -s 15 1 && (sleep 10; kill -s 9 1)'
ENTRYPOINT ["python","./HoymilesZeroExport.py"]

TASMOTA TTL reader setup (like bitshake ESP8266 with HOLLEY e-meter):
USE_AHOY = true
USE_TASMOTA = true
AHOY_IP = 192.168.xxx.xxy
TASMOTA_IP = 192.168.xxx.xxx
TASMOTA_JSON_STATUS = StatusSNS
TASMOTA_JSON_PAYLOAD_MQTT_PREFIX = DTZ541
TASMOTA_JSON_POWER_MQTT_LABEL = curr_w
TASMOTA_JSON_POWER_CALCULATE = FALSE
TASMOTA_JSON_POWER_INPUT_MQTT_LABEL =
TASMOTA_JSON_POWER_OUTPUT_MQTT_LABEL =
USE_TASMOTA_INTERMEDIATE = false
