Have you installed HA as a docker on iHost? Well, it is not the same as other installation options, e.g. on RPI. Mainly because there are significant limitations on iHost. You quickly reach a wall and the fun is over. A better idea is to use iHost as the HAOS hardware platform. Unfortunately, this project has recently been stuck on a serious Ethernet port problem. There’s more about it in this thread.
Almost all tutorials from eWeLink are out of date. With particular reference to those concerning integration with HA. eWeLink has even stopped developing the official integration with HA. With the continued development of HA, this integration sucks.
