I've done this and it works well. I'm upgrading to some pro 3s for mains and AC circuit monitoring. The Shelley em does a good job but I'm looking for a quicker response cases and want to monitor individual AC circuits. The 1pm works well for larger device monitoring and control. I was using it to control a hot water system but it had a short life as it was quite hot where I installed it. I coupled it with the add-on to monitor hot water temps to turn it on and off. I also use them to monitor water pump temps for the pool and an irrigation pump.
I use home assistant for energy use visuals and control as find my old phone is slow to load the Shelly app. I still use the original wifi plugs (similar to U) as I still like controlling random devices like tv and screen time.
