I'm in the market for a geothermal system and like a lot of things I've found about the Waterfurnace Series 7 units. One thing I'm not fond of however are the limited options for monitoring and controlling the unit over my local network. From what I understand, the Aurora WebLink router and Waterfurnace Symphony service provide remote monitoring and control but only through the Waterfurnace Symphony cloud service, not directly through my local network. I'm not prepared to turn over control of my unit to a service provided exclusively over the Internet. There are several reasons for these concerns with security of the system and my network being chief among them. I'm not saying anything bad about Waterfurnace's security, having never used or evaluated the security of their products. It's just that I'm not interested in taking that risk with this system. I am looking for options that allow a similar level of monitoring and control that can be managed completely within my local network, requiring no access to the wider Internet. The preferred solution would be something that is already supported by Waterfurnace but I'm interested in considering other options as well if this capability isn't available from them. For anyone here who has the Aurora WebLink (AWL) router, have you found any way to accomplish this? I've seen mention of a locally accessible AID Tool feature built into the AWL but the information available through that interface appears rather limited from the few screenshots I can find. Could anyone provide a first-hand account of what is possible through this interface? The manual for the AWL mentions that the original SD card contains information that is important for connecting to the Symphony service. It goes on to say that removing or replacing the SD card will disable access from Symphony. Has anyone explored options for local control under such conditions or with changes to the information on the original SD card? Also, if anyone has examined the network traffic from their AWL, what insight has this provided about the system and the possibility for local monitoring and control? To be clear, I'm fine with a fairly raw interface. No need for a pretty web UI (or any UI really). As long as I can access and control the unit through a reasonable protocol or API within my network, I'm fine with that. Ultimately, I would like to integrate this into my OpenHAB home automation system, so that would become my UI. Needing to write scripts to interact with it (over a TCP socket connection for instance) would be a perfectly acceptable solution if that's the best option, as long as the communications do not rely on a cloud hosted service over the internet. Finally, as a last resort, I've seen discussions here in the past about decoding the custom Modbus traffic from the Waterfurnace unit directly and interfacing with the unit that way. @geo_jon (and several others) even mentioned reverse engineering this protocol and he shared a link to a website where he publicly posted live information from his unit at some point in the past . I couldn't find any detailed information posted about this however and the linked website appears to have been taken down in the years since he posted it. Waterfurnace, If you are reading this, know that there are many people out there that are interested in this. An installer I spoke with said that he hears requests for local access (without the "cloud") on a regular basis and would love to be able to offer such a solution. I hope such a solution exists or can be made available for those of us with these concerns.
