well, I allready bought it (hence the pictures 😉) wifi spots can only communicate over wifi… most don’t have an ethernet port to direct connect your gateway. so they always use max current many of them have very limited dashboards settings. _just my 2 cents 🙄_ _\* that last link is interesting_ ---
