I followed the advices above and got readings using Putty from the P1 port of the smart meter: T210-D ESMR5 ESP-Easy version ESP_Easy_mega-20191003_normal_ESP8266_4M1M.bin on a node-MCU, circuit and parameters as shown by Domosapiens and DomoticaRob, Domoticz (running on a Synology DS212J) : P1 Smar...

So there is no wake-up possibility in ESPeasy after let's say 1 minute?
Try to connect GPIO15 to RST, since that pin goes low after the deep sleep timer ends.

> This i can do of course with max sleep time and GPIO16 ?? connected to RST. I guess you mean GPIO15. I am doing excactly the same to find out what batteries I should use (NiMh) for maximum service, no pull-up resistor needed. Did you try shorter wake-up periods? Make sure all your code is in the s...

ESP wakes up from deep sleep by the connection of GPIO15 to Reset - GPIO15 goes low when deep sleep ends.
You can also wake up the ESP manually by driving Reset low some other way.

There is a library ... I think SyncClient should do it?

or this one?

So how if I may ask ..?

Sorry to be rather ignorant, I hope my question is clear enough: I am using a TCP protocol to dump temperature and time data to carbon database to feed Grafana using Arduino software. Only an IP address is necessary for this operation. Would it be possible to include this protocol in the ESPEasy Con...

What would shorting to the ENABLE option do?
