Smart Meter Script for S0 Interface

[TBR-BRD]

Is there an example for the integration of a meter with S0 interface? https://xn--stromzhler-v5a.eu/stromzaehler/wechselstromzaehler/fuer-hutschiene-ungeeicht/66/sdm120-pls-1-ph.-wsz-fuer-din-hutschiene
It outputs 1000 pulses per KWh.

Hello, do you have a working example in the meantime? Thanks!

The documentation says that 5 meters can be connected, but is it possible that only 2 couter are possible?
When I try 4 counters with S0 in the script, the ESP crashes and when I reboot, script enabled is off.

[gemu2015]

please post your script, i will check what is going on. MAX_COUNTERS is predefined to 4, so 4 counters should be supported.

Here the script. Tried with ESP8266 with 4 and 16Mbyte memory

ok you did choose "forbidden" pins for an ESP8266
at least with "allowed" pins it does not crash.
you may choose e.g. pins 12,13,14,15

[steand]

pin 15 (D8) isn't a good choice. D8 has a pulldown an must LOW at boot. If a external pullup exist the ESP2866 didn't boot.
Better use: 4,12,13,14.

This works for me:

1,1-0:1.8.0*255(@400,Bezug,KWh,Total_in,3)

I want to use that script to monitor my heat pump energy consumption which has an S0 meter installed before
circuit breakers. Is there any instruction how to do the wiring at ESP8266/Wemos D1 board with Tasmota?

[Juhe0167]

Hello,
I will also control the power consumption from my heat pump.
I use an ESP Wroom32 with Tasmota 13.2.0, an created a counter on GPIO15.
It is counting and I can see it on Grafana, so MQTT works.

I use this ESP32 and Tasmota allready for measurement with DS18B20-sensors and it's working fine.

I'm sorry, but I do not understand how to get the rest running.
When I try to copy the Scipts in this thread into the Berry Console, I always get an error message, f.e.:

D
B
=>sensor53 r
W
;<style>form button{display:none}</style>
M 1
+1,14,c,1,-40,WP
1,1-0:1.8.0255(@1000,consumption,KWh,Total_in,3)
1,1-0:1.7.0255(@0.01667, power,W,Power_actual,0)

BRY: Exception> 'syntax_error' - input:1: unexpected symbol near '>'

Sorry, the > is not typed here, but in the scipt...

Whats wrong?

I've read a lot, but do not get any advantage.

Maybe, someone can help me or give me a working scipt.

[sfromis]

Berry is a very different language; what you have there is for the older scripting feature, which is only available in the tasmota32-scripting found here: https://github.com/Jason2866/Tasmota-specials/tree/firmware/firmware/tasmota32/other
(Also available in the Tasmota web installer under "unofficial" binaries).

[Juhe0167]

That's it, I installed the ESP new with the scripting-version an now it is working.
Thanks a lot.
