Are you running the default sketch? What arduino ide do you have? What version of esp8266 library are you using?

@carlyler thanks for the explanation. That's an interesting way of charging for electricity... The "virtual sensor" had me a little confused as it is also used to create real virtual devices in Domoticz. I think you handled it the royal way. Although you could argue that the "calculation" should take place in the controller. Have fun and when you designed a way to lower your electricity bill let me know :smile:

I've had the exact same issues. Tryed every possible fix but dint work out for me. I really liked the interface of MyNodes.NET but the lack of support just forced me to choose another controller. Will check regularly for updates but wont expect much. Hope it will be updated once again :)
