I was quite surprised to find the doorbell from Simplisafe wasn't as simple to install as the rest of the range and didn't allow you to add chimes in different parts of the house. Luckily I found that Ohmkat make a kit that does just that and makes installing and powering the doorbell quick and simple with no need for an electrician! I had the whole thing set up within an hour. I was concerned cost might be prohibitive given we were ordering from the UK, but when you take into account the cost of paying an electrician to wire in a traditional chime and the benefit of having extra chimes in the garden building and upstairs it was actually very good value. I would definitely recommend the kit and Ohmkat were very quick to respond to questions with useful advice. The parcel arrived within a week, even over the Christmas holiday.
