You could get a lot of mileage from the Espruino Wifi maybe speak with @Gordon (Espruino creator and Official board supplier) before you write it off - but as you say Rasp Pi, particularly Zero W, is the other option.
One question if I may, how do you get on with approval/certification. The benefits of your solution are very clear - I checked your website - but the insurers always seem to be about risk assessment and ass-covering. If you would share how you approach this it could help others with your skills, put them to equally good use.
