If your Home Automation (HA) software has a driver to read weather data from The Weather Channel (TWC), it probably uses TWC's free 'XML Data Feed' service. I received a notice from TWC announcing that this free service will end on October 31st.
I suspect that, on November 1st, your HA software's TWC driver will probably display erroneous data if anything at all. Your TWC driver will require alterations in order to support TWC's new data feed service, called The Weather Channel API. Moreover, this new data feed is not free and requires a subscription; the least expensive plan is about $20/month. You may want to contact the manufacturer of your HA software, or the TWC driver's developer, to determine what plans they may have to accommodate the new TWC API.
TWC does offer free alternatives in the form of a Weather Widget (see bottom of the API page) however it is not a true replacement for the XML Data Feed.
