It is not 16A as it appears from the photos, but 15A. It works perfectly, with the company's classic rich software. I would say that there is a small confusion regarding the specs. For example, I mentioned the amps, on the board it says powR2, the software also recognizes it as powR2 but it is not written on the packaging as R2. I connected it to a water heater, to a relay, parallel to the switch on the panel. It works great, either remotely or with the classic switch/fuse. In the software recordings, I saw it reaching 16.25A and fluctuating there, definitely not below 16+A and not above 16.3. It works without any problem. It's worth it.
