I am using Helio heaters, but there does not appear to be a way to keep track of the temperatures remotely. The alarm going off when I'm not home isn't very helpful. Is there a stand-alone temperature tracker that will connect to Mobius? I got an Apex and that works, but this is for my 40 gallon, which is in a different room from where the Apex will be, so I don't think possible to connect. All the searches I've done here are really about heaters that will connect to Mobius, but I'm looking for a stand-alone probe to keep track of temperature, not control it.
