Hi there,
I'm embarking on adding meter readings (gas, water, elec) to HE, so that I can decide what to do with my PV generation, spot water leaks etc etc.
I'm using an ESP8266 with an LM393 to count meter pulses.
I tried with Tasmota which was looking good, but hit a wall (see Creating a power meter by counting pulses with LM393 and Tasmota - #2 by jamesxheath and [RELEASE] Tasmota for HE - Auto-detecting Tasmota drivers + Tasmota firmware 7.x/8.x for HE (for use with Tuya, Sonoff and other ESP devices) - #586 by jamesxheath).
Then @peterbrown77.pb reminded me about HubDuino - of course!! I already have that set up for a load of DS18B20 temp sensors.
I'm working on getting the pulsecounter working, but have hit an issue - I don't think the ESP8266 is getting data to the HE - the child device hasn't been created, and the logs show nothing interesting other than an error:

which I think is because the Hubduino parent has never received data, so doesn't have a time stamp to work out the presence from.
In my arduino code I am using the identical settings to my other devices, with the exception of the reserved IP for the 8266 (which I've checked is correct).
The arduino serial monitor is behaving a bit oddly (weird non ascii chars):
Enter the following three lines of data into ST App on your phone!
localIP = 192.168.86.25
serverPort = 8090

(I have obfuscated the Wifi details - they are correct)
It suggests that it is trying to send data, though should I worry about the line:

This ESP8266 and the pulse counter worked perfectly on Tasmota - I could see everything over Tasmota's webUI - I just couldn't get the data to appear in HE
Help!!
