Hi all, I have two Ignition sites connect to one another over Wireguard VPN tunnel. These two sites both have LTE sim cards with a current 10GB data cap ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/8/e/8e7be68c11a824d4a9ab377c0377fa583691de09.png) This is the usage after 3 days, ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/2/7/277698b6c5e965e227fc2a7adea47c77e428fdc8.png) I created a another tag provider which just contains reference tags of the data I want to transmit, it currently has a total of 92 tags (52 Boolean ,40 Float and Integer ). In the service security I have denied access to all the other servers and only allowed assess to the Remote Tag Provider. Is there anything else I can do to reduce the data usage? ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/0/f/0f8206f9caca2439a2f2c1c10fb9b5584ff9d792.png) ![image](https://us1.discourse-cdn.com/inductiveautomation/original/3X/5/9/5938d5461a615a3a094194437fe5784a9aaff1ff.png) I know mqtt would have been a better option in terms of data usage here but this is what I currently have setup. ---

Out of curiosity, have you tested with NO tags being shared, just to see what the baseline data transfer amount is? ---

I don't have any measurements of my own to back this up, but I am pretty sure GAN is the least efficient in terms of bandwidth of the 3 obvious options (GAN, OPC UA, MQTT+Sparkplug). Configured correctly OPC UA can be a closer match to MQTT+Sparkplug than many would think. If bandwidth is top concern I think MQTT will still win, but you need a broker and/or the MQTT modules. ---

Okay I will try the OPC UA option ---

You should also probably figure out a reasonable approach to measuring these, e.g. establish a baseline like suggested, same number of tags, stable-ish number of tag changes happening, etc... ---

I'd probably start with that type of testing. Figure out what your barebones overhead is- What's just the wireguard connection going to cost you, without even having the gateway network. Then what's the gateway network add. Then what do the tags add. If 1 or 2 burn all your data, then it doesn't matter much if you optimize the tags...
