SOLVED: ESP-01 driving me crazy.....

No I'm not using softwareserial on 0,1...
And I am connected. The sensor is happilt sending data over Wifi to MQTT.....Great success !

Just starting out with this IoT stuff, and it's fun.
When it works.
Any hints on where to find documentation on how to use the uno as a slave to the esp ?

Didn't know that was possible, but for now I don't see how I can achieve my plant watering system without the help of an arduino to control my relais....
