My initial plan was to get my $50/month water heater rental bought out and have a reverse osmosis and softener installed. But after seeing the what I could get for a few $$$ more per month, I decided to get the Google Nest doorbell cam, outdoor security cameras, and nest thermostat.
There were separate installers that installed the water systems and the Google home automation equipment. All the technicians were very professional and courteous.
In the end, it was a very good deal and I am very happy to have gotten rid of my water heater rental bill.
