The device the OP puts Tasmoto on from athom.tech can also be ordered for the same price pre-flashed with ESPHome to work with Home Assistant. I have used them with 2500W single-socket loads and been happy with them for a year or so.
For whole house load I'd recommend integrating with whatever smart meter tech your country uses.
For the in-between size loads eg. 32A breakers in a consumer unit I have not found a reliable and cost effective solution yet.
