New installation did the job

I updated to 4.9700, and nothing works anymore. I took an old back up with V3.8153, and it works again. Only the notifications are not working anymore. The log file gives: 2018-07-21 16:17:30.584 Error: Prowl: 2018-07-21 16:17:30.585 Error: Notification sent (prowl) => Failed 2018-07-21 16:18:05.022 ...

Uiteindelijk is het mijzelf gelukt:
sudo date -s "Mon Jul 2 19:40:26 UTC 2018"
En de datum en tijd staat weer goed.

Edit: Excuse me, in English:
I found out myself:
sudo date -s "Mon Jul 2 19:40:26 UTC 2018"
did the trick

I’ve had a problem with domoticz, so Now I use an old image file from domoticz. I made the image in january. Now the time and date are from january. I tried several linux commands to change this to the right date, whithout succes. Does anyone has an idea what to do?

There is nothing you have to do onthe Domoticz PI. On the Homebridge pi you log in tot the Domoticz pi (first install the domoticz plug in). On the the you can install Eve. Then in the app “woning” (in dutch) you can see al the domoticz swtiches.

I bought the app, and it is working! I tried a lot of things to get the apple working with Domoticz, and this app is very easy to use. On your apple device you have to install Eve. I have 2 Raspberry PI’s. One with domoticz, and one with Homebridge for Raspberry PI.

And suddenly it works again......

Hi. Updating today to IOS 11.1.1, I can not open Domoticz anymore. I also have the Idomotic (for IOS) wich also does not work anymore.
On my android and on windows there is no problem.
Anyone a suggestion?

That's the trick.
Thank you, SweetPants!!

Hello,
I have a backup Raspberry PI. When I start it (with a copy of Domoticz), I get a black screen. In the upper left corner there is a double point and a pull down menu. The pull down menu is empty. I have made a new SD card wih domoticz, but that doesn't work.Does anyone know what to do?

You' ve made it very clear. The blocky' s are working now.
Indeed, it looks simple, but if you make a mistake, its hard to find the mistake.
Maybe its time to take a good look at Lua for me.
Thank you all!

Thx for the reactions. I checked is and "Open" and "closed" are right.
Mr simonrg: You put me in the right direction. For "Open" I now have the following Blocky, wich is working now:
Thnx for that. Now to figure out how to handle "Closed"

Hello, I reckon myself as a starter with Domoticz. I have been looking al over this forum for an answer. I hope anyone can help me. I have two contact switches. If one of them is "open", I want Domoticz to switch on a light. If they are both closed, the light must be switched of. I have 2 blockies ...
