+	; starting sequence:

+	;- restart Tasmota with script sctivated (you have 5 minutes to do this)
+	;- after 30s first 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!
