The HS300 is fully compatible with Sense - I use 3 of them. But I was looking the other day, when I answered your earlier post, and I didn’t see a UK or European version of the HS300. The KP303 is a very different product both in the US and UK.
- 3 outlets vs 6
- NO POWER MEASUREMENT CAPABILITIES
- From what I can see, the HS300 is a 120-only device.
You might need to use one of the compatible model single outlet power-sensing plugs like these (KP115 is supported by Sense in US), used with an outlet strip. Not quite as useful.
This model is also energy monitoring but the model number doesn’t exactly match up with any of the Sense tested models (Sense does support HS110s).You might need to buy and try.
