OK, I found out how to ping.
The IP address blynk-cloud.com is 139.59.206.133
I enjoyed the IP and nothing changed.
I believe it can be done without Node-Red.
the error will be in the syntax
http://139.59.206.133/xxxx/update/V1?value={customData#wight}&...
or
http://139.59.206.133/xxxx/update/V1?value=wight&...
what is the way to claud for example for virtual variable V1?
and how to assign a value?
