I was reading the referenced thread today and as a former IRIS user I have some thoughts on the subject. As most know IRIS is no more. Lowe's is a big company and had the money to reimburse users for some or all of the devices users purchased. As far as I know Lowe's never gave a reason for dropping IRIS. I assume that it either was losing money or just not profitable enough. One obvious possibility was they offered to much for free. I was one who took advantage and never signed up for a premium service as my needs were satisfied by the free options.
Now I have invested time and money in Hubitat. My hope is it will be the last HA and Security system I will purchase. To survive Hubitat needs a steady income stream. Eventually the sale of hubs will not be sufficient to provide that income stream. Premium services are obviously a way to provide an income stream.
In the referenced article Hubitat said they do not plan to "bait and switch" their users by starting to charge for thinks they now provide for free . Great! However they already provide almost everything I want for free and if they keep adding more.......
My point is I don't want a repeat of the IRIS situation. I don't want Hubitat to someday go the way of IRIS because they didn't have a steady income stream. I don't expect them to reveal their "secret plans" but rather I just hope they have a plan for the income stream that will be necessary for them to survive long term and I don't think just selling hubs is the answer.
Just my opinion and you know what they say about opinions.
