Hello,
A happy user of the new Shelly PLUS H&T, actually 2 of them. I operate these two devices in my localnet without the cloud. For this I set up a local NTP, which I can confirm works:
$ ntpdate -q 192.168.x.x
server 192.168.x.x, stratum 2, offset -0.018502, delay 0.02803
1 Sep 15:17:32 ntpdate[3400]: adjust time server 192.168.x.x offset -0.018502 sec
The only issue is that the updated Shelly PLUS H&T Firmware still lists the time for the above as 13:17:32. I checked, I have properly set the timezone settings (+2h), so no idea how to correct this... Any advice much appreciated!
