My immediate thought is, does it use exactly the same r.f. settings as we do, with the same message protocol and the same encryption key? If it’s got a Hope RFM69CW inside, there’s a slim possibility that it might work with your emonBase. The second thought is, can it be made to be the same, with new software?
If not, the problem becomes one of knowing which type of message is going to arrive next at the emonBase, so that the emonBase can set itself up to receive it - and this will be a near impossibility even if you know how to decode it.
So I think the realistic answer is no, it cannot.
There’s also no mention on their website of anything other than their (proprietary) web access, I get the feeling that they’ll have deliberately made it difficult if not impossible to get the data by any other means.
Your likely only method will be to set up an account at AcuRight and ‘scrape’ the website for your data.
Of course, the much easier answer is right under your nose: emonTH -Temperature & Humidity Node - Shop | OpenEnergyMonitor
