TRV http command issue

Ciao.

i have shelly trv which sometimes doesn't execute http command

example :

http://10.0.0.70/termostato/0?pos=100

http://10.0.0.70/termostato/0?pos=0

he doesn't seem to wake up

Thanks

ok , but i can't ping from shelly 1 or control4 ip driver. shelly1 syntax seems correct to me.

?

so shelly1 is not good at sending http commands to TRV ?
