Hi, I'm installing a Hydrosys4 system on a property where wireless internet connections are very weak. I'm trying to sort out a long range antenna to help but I'm wondering about this:
If I setup the system, then connect the Hydrosys to the internet via mobile phone tethering with the correct time zone and then I disconnect from tethering, does the Hydrosys4/Raspberry pi system keep time as best it can until it's next connected to the internet and then adjust for any seconds gained or lost?
I'll check it in a few hours and post actual state, and one more issue with dht22, actualy 2x dht are connected+bmp180+bmp280. About 3 weeks has all worked perfectly and now no data from dht in graph in DATA page. But in SETTINGS page reading the sensor working ok. a few days ago was in graph a "jump" on dht line, streight line betwen two time points, now only bmp lines left.
