The transmitter from my unit has failed and I am hoping someone has one they aren't using and are prepared to let go cheap... Don't even need the display - just the transmitter... Worth asking I guess :-)

Yes I could make something up to do the job but what I had worked great.

Saying that - if anyone knows of a simple replacement product please let me know. I don't need a screen, just serial or mqtt type output.

Cheers - N

I have the same setup, data from Envi-R transmitter converted to MQTT.

I had two sets, but the first transmitter broke due to water ingress. I'm now using my remaining transmitter.

Hope you find a replacement.

Hey, I might have the clamp meter sitting around in a box somewhere. Give me a day or two to see if I can find anything.

Glad you are sorted.

Can I ask how you are interfacing the signal from this to mqtt/serial? Are you using the display and adaptor > USB, or SDR, or something else?

I have a similar setup but am looking to streamline.

Thanks

I checked again and I am actually running a python script on my homeassistant box getting the data by serial and dumping it straight into an Influx database.

#!/usr/bin/python

# Reads data from a Current Cost device via serial port.
# Parses the XML to extract the temperature and the electricity consumption
# Adds data to InfluxDB database.

import os
import serial
import re
from xml.dom.minidom import parseString

# open the Serial port at 57600 baud, with a timeout of 3 seconds
# /dev/ttyUSB0 is normally the first (lower) USB connection on the Raspberry Pi
# Check ls -l /dev/ttyUS* after plugging in the RJ45 to USB cable and
# ammend accordingly

ser = serial.Serial(port='/dev/ttyUSB0',
baudrate=57600,
bytesize=serial.EIGHTBITS,
parity=serial.PARITY_NONE,
stopbits=serial.STOPBITS_ONE,
timeout=3)

while 1:
line = ser.readline()
if line:
try:
dom = parseString(line)
except:
continue # if we get a corrupted XML line then ignore and continue (wait for next one)

# get the temperature <tmpr>
try:
xmlTagTemp = dom.getElementsByTagName('tmpr')[0].toxml()
xmlDataTemp = xmlTagTemp.replace('<tmpr>','').replace('</tmpr>','')
except:
continue

# get channel 1 and then the watts
# you may need to change the occurences of "ch1" to "ch2" for your display.
try:
xmlTagWatts = dom.getElementsByTagName('ch1')[0].toxml()
xmlDataWatts = xmlTagWatts.replace('<ch1><watts>','').replace('</watts></ch1>','')
except:
continue

influxstring = "curl -i -XPOST 'http://[DBip]:8086/write?db=poweruse' --data-binary 'kwh value=" + xmlDataWatts + "'"
os.system(influxstring)

In my case, I hooked up an SDR to RPi and use some opensource 433Mhz library to receive and process the data and then throw it as MQTT.
