mqtt on esp32 need a lot of memory, better use a rest api call with a small python script.
sample:
# simple rest get message for all watermeter data
# (disable this if you do not need rest service)
- platform: template
id: watermeterdata
internal: true
disabled_by_default: true
lambda: |-
char buf[128];
sprintf(buf, "%.3f|%.3f|%.3f|%.3f|%.3f|%.3f|%.3f|%.3f|%.3f|%s",
id(waterdisplay).state,
id(current_value),
id(hour_value),
id(daily_value),
id(yesterday_value),
id(week_value),
id(watermonth).state,
id(lastmonth_value),
id(year_value),
id(systime).state.c_str()
);
std::string s = buf;
return s;So you can get the data with:
curl -i http://water-meter-esp.local/text_sensor/watermeterdata
HTTP/1.1 200 OK

Hi everyone I would like to ask you some information I followed this project.
wmbusmeters hears nothing except 169Mhz telegrams in n mode. It's probably the electricity meter. I don't need this meter but I would like to read the water and gas meters. These meters probably transmit at 430Mhz. They probably only send a few telegrams monthly. So I would like to put wmbusmeters to listen to all telegrams transmitted at 430Mhz and send them to MQTT. Then I write a python job that goes to MQTT and if it finds something it saves these telegrams somewhere, so I can easily check offline. Is it possible to put wmbusmeters in this generic reading mode? If so, can you tell me how?
Thanks in advance.
I apologize for my English which is probably not perfect.
