Hi, I'm trying to synchronize data between a Central Gateway and an Edge Gateway. The idea is to have permanent data on the Central Gateway while the Edge will be limited to it´s capacity, which today is being about 10 days. The history data is arriving on the Central Gateway but the problem is it´s not storing beyond the available data on the Edge. It´s being a mirror of the Edge history. On the central gateway I configured a History Tag Provider like bellow ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/6/861024c1cfbb1ecb76dae6b7f3c728e957b2f516.png) but it´s showing a faulted status, even considering that I can see the history on a PowerChart. But as I said, limited to the amount of data in the edge gateway . ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/9/4/94fd5362dfa2372a5dc694320be27ee8a8da70f4.png) ---

You should have the historian on the central gateway, and the edge node connecting to it remotely. Have a tag history splitter on the edge to send data to both the remote historian and a local historian ---

Hi, I have had some progress but still a problem. 😒 Now the data is going from Edge to the database in Central Gateway 🙌, but when I try to plot it in powerchart it shows only a line. It seems like it´s showing only the last value, the line keeps changing it´s position. Is it really possible to show data from databases on powerchart? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/7/9/79ce4411b0fcce2762425dfe35d176453d1c7647.png) Obs.: You said about a tag\_history\_splitter but I didn´t find this option on Edge. I'm doing it on Data Sync / Settings, where there´s onle way to put one "Remote History Provider Name". ---

It sounds like your configuration is scrambled in non-obvious ways. You should open a support ticket so IA can look over your shoulder. ---

Hi, sorry for the delay. There was no problem with the configuration and it worked the way it was in the end. I saw later that the straight line only appear in first time I was accessing (plotting) the data. I guess it was kind of a bug. Usually I just needed to update the browse tags and wait some seconds for it to be plotted correct. I don´t know how, but it´s not happening anymore. Maybe because at the begginnig there was a bunch of previous data on the edge to be sent to the central database.
