I have bought a hubitat to replace my homey.
Now I have two problems, I can't connect my Tado V3+ and my Somfy I/0. I have downloaded the drivers but they not find my LAN devices.
Is there somebody that can help with this problem?
If you mean you're navigating to the hub's "discover devices" page and then clicking on "LAN devices," that will not work for devices that require custom drivers developed by the community.
Actually from the available info that OP has posted so far, I canโt determine whether he has installed the required custom drivers/apps correctly for these two community-developed integrations.
My suggestion is we clarify this point first because otherwise weโre kind of shooting in the dark re: other troubleshooting steps.
Still can't tell if you've taken all the steps required to correctly install and configure the tado integration, which includes a "connect" app that I believe is required to make it function as intended, as @bobbles has mentioned (i.e. it's not just a single driver). See here and please confirm you've followed these steps in order.
I almost went with a connection myself, but ended up getting a Bond Bridge which has a community developed app / driver. From memory there was a REST API for the connection, so I would expect we could write a driver for it. Do you have any preference? I'd be happy to take a look, but am particularly slow in turning stuff like this around.
