Hi, I am a new user of home assistant and I’d like to get the results of my eBZ DD3 Drehstromzähler too. My setup differs, I do use an ir sensor connected via USB to my computer. I can access the results of the smart meter. A simple ‘cat /dev/ttyUSB0’ shows the results, like “1-0:1.8.0255(000229kWh)”. Of course, my smart meter does not yet show all data, I am still waiting for the pin.
Can you please help me what do I have to change in your code to get the results from the serial port without using ESPHome?
No offense and don’t get me wrong, but don’t you think it would be easier to just spend 30 bucks on an UART sensor and an ESP8266 to have a working template instead of asking for detailed help on a kinda different subject in apparently the wrong thread?
Sorry for asking here, but for me it looked like it’s an “easy” task to adapt the configuration.yaml to use a serial port instead of the esp8266 stuff.
On the other hand, I#d like to learn about home assistant and saw that this project uses a complete other configuration.yaml syntax than the one mentioned. My hope was to understand the project as good as necessary to adopt the configuration.yaml to use a serial port instead of ESP8266.
And reusing available resources is imho better than buying new ones.
Hi, do you mean as an official component of esphome (instead of an external component)?
Well, I have some experience with that and it always caused me a lot of extra work, with less flexiblity. As I do this in my rare spare time I don’t want to spend more time at the moment. Sorry.
Quick note for anyone trying this on an esp8266:
The regex checking is very slow, when using it for all sensors (in my case 9 sensors, 2 for energy, 4 for current power (total + 1 for each phase), 3 for voltage on each phase), the esphome device (esp8266) loses Wifi from time to time and will fail to show logs in esphome and also fail to update via OTA.
Easiest solution is just to use the regex checking on the “important” sensors (e.g. the energy sensors) and not use it on the instantaneous sensors (power, voltage) as those don’t tend to cause issues if they might show a wrong value once in a while (although so far it seems to be rock-solid)
(or of course you could use an esp32 to get the required horse power )
nice component, worked directly out of the box - thank you.
But I have a problem,
the entity for “power” does not provide a value.
yes, i unlocked it with the PIN and the actual power value
is shown on die Display of the smart meter.
The software runs on an d1 mini (az delivery).
FYI: My smart meter (different vendor) has the following problem: It forgets the INF configuration when there is a power outage. So I always have to reconfigure…
Dear all,
thx for this nice component - unfortunately it does not work for me
Hope you could help me: No matter what I do, I always get "[22:30:00][D][obis_d0:152]: abort"
in the logger. I tried different things, but apparently the data is not comming through. Using NodeMCUv2 (ESP 8266) with the exact example as given by judges.
Any idea where I should be looking at?
Update: Found that my meter uses SML and code 1_8D_0P_N_1S for serial coms.
Meter name: ebz dd3 2r06 dta smz1
How do I activate that in the above example? Thx!
ESPHome is using a different approach than Tasmota: ESPHome doesn’t a provide pre-build binary, but let you build your own application based on your needs. Therefore, please get familiar with ESPHome.
