+	; frequent requests will lead to blocking and reduces lifetime
+	; starting sequence:
+	;- press button on device once
+	;- restart Tasmota with script activated (you have 5 minutes to do this)
+	;- after 30s data is retrieved and logged (including SYSLOG depending on Tasmota log config)
+	;- now every 45min a new request is done, updated in WebUI (and transferred by MQTT every TPER period); polling period needs to be less 60min to avoid sleep mode of device!
