Does anyone know a free provider for MQTT with good representations of measured values?

@felmue
Yes thanks, that can not work I have only the free version, thus without MQTT at Thinger.io

I bought a M5PAPER and want to exchange data with UIFLOW via MQTT with the provider thinger.io.
I have tried a few things, but I can not do it.
Does anyone have experience?

Thank you, world101, for your quick response.
Now Blynk works at my M5STACK.
Your Blynk.m5b has five UiFlow blocks for only three virtual functions.
But Blynk offers much more features.
Has anyone already generated more UiFLOW blocks they can share?

Hello, world101 I am very new here in the forum and want to control my M5STACK with "blynk" via UIflow symbols.
I use:
UiFlow V1.4.3
F5STACK fire, the red one.
blynk for Python v0.2.1 (esp32_LoBo)
MicroPython ESP32_LoBo_v3.2.24 - 2018-09-06 on M5Stack with ESP32

I have successfully worked through all the above points.
However, the dispaly from my M5STACK shows the following error message:

error
ImportError("no module named 'uiflow'",)

I think that I have not installed the above mentioned elements:
"machine, time, m5base, uiflow"

In the boot.py I have edited the following, as you have described above:
import sys
sys.path.append('flowlib/lib')
sys.path.append('/flash/blynk')
import machine, time, m5base, uiflow, BlynkLib

I would like to implement remote monitoring via iphon of my groundwater pump.
It would be nice if you could help me, please.
