I am looking options for communicating securely between two instances of node red across the internet. Open one of the NRs to the internet. I don't want to do this if at all possible. I am not happy that the s/w is mature enough yet to be confident that this is secure. Use Telegram. I was h…

Hello Colin From your description I guess that both node-red installations are in two different local networks, connected by firewalls/NAT to the public Internet. Since node-red and MQTT have concepts which fit to each other (messages and topics) I think this is the best way to go. You need to ru…

Thanks @Urs-Eppenberger , I believe I know how to do it. I have a server in the cloud that I would run the broker on, then I don't have to let anything into my local networks. I think I will probably go down the MQTT route since so far the only other contender seems to be pushbullet and that does n…

[image] Colin: Any other suggestions? Hi Colin, have you considered using dweet ? Dweet - M2M

Colin, If it is only point to point then i would either create a VPN between them or nail up an SSH tunnel and use that. Probably dont need to tell you about VPNs - but an SSH tunnel will let you send a single (or multiple ports) between the two machines - so for instance anything sent to (say) po…

Alternatively (not knowing your platform) - a quick and simple OpenVPN VPN - if Peter recommends it - it must be good !!! [image] PIVPN and PI-HOLE - Scargill's Tech Blog Before we start, here is a link to the PIVPN site http://www.pivpn.io/ also to Pi-hole: https://pi-hole.net/ and thank…

If you need to connect two networks, I personally would use a VPN or, more likely, an SSH tunnel if you are only looking to connect a couple of ports. Either way, you will also need to make sure that you lock down the connection using firewalls at both ends with tightly controlled connections. See m…

I am thinking that an MQTT server is probably the easiest way, and I don't see any security risks.
