So many Inteon users seemed to turn to ISY994i. i have several question to consult:

- is it easy to setup?
- is there phone app for use?
- is it compatible with my current insteon devices: dim switch, motion sensor, insteon alarm?
- what model of ISY994i need to buy? Do i need anything extra to make it run?

You may want to look and ask in the UDI Forums and their web sites.

Since you are using Insteon. It will need a 2413S PLM. Which model you want may depend on how many devices you want to use. One nice thing about the ISY994i is if you need extras. You can add then yourself. So lets say you need to have the PRO version. It can be added by you by purchasing the PRO add on. Same for things like the Portal access. Even a Z-Wave card.

The users in the Forums are very helpful and UDI has one of the best support system I have seen in a long time.

Easy to set up? That is relative. I suspect most find that it has a learning curve. Plan to spend more than a couple of hours. You will have to play around with it a bit to get good at programming.

Phone app? Yes...a couple,..but they are additinal cost.

Compatibility..for all practical concerns, it is compatible with all insteon devices, past and present.

UDI has been around for ever and people really like it.
That said, I bought it and returned it about 2 years ago, because:
-there is a learning curve
-it is old and clunky software and hardware (serial)
-can't be used if you also have an Insteon HUB
-Alexa integration costed extra monthly and you can't use your HUB
-it still relies on the Insteon 2413S - which is prone to failure, overpriced

I decided to try open source solutions:
- OpenHAB -
- Home Assistant -
- perhaps others

and finally settled on running a raspberry pi with Insteon 2413U USB Modem (probably still prone to failure but at least it is USB) and using:
- insteon-mqtt -
- with node-red -

My setup has a slightly bigger learning curve than UDI but...
It is modern, flexible and allowed me to expand to integrating:
- ecobee thermostat (when my Venstar insteon thermostat died)
- another ecobee for a second home
- the smartmeter on my house
- Genie MyQ garage door opener (Genie is a closed system but someone hacked it and shared)
- Google DNS so I can always reach my system by
- Blynk
- devices (arduino-like, custom, wifi and cellular devices)
- Azure, AWS, Google, and IBM clouds - although I'm not actively using these - it was just to learn

In my system, adding and deleting devices is a bit wonky, where you have to use the button method and then edit a configuration file in insteon-mqtt to reflect the new equipment.

But the programmability and expand-ability of Node-RED is unsurpassed - just amazing. Makes the wonkyness all worth it and it salvaged the thousands I had invested in Insteon and was thinking about tearing out and switching.
