| I posted this over on the Home Assistant forums, but thought I'd have more luck here....
I have a ton of Insteon devices in my home and have also started looking at some Sonoff devices as well. I also have an idea for a custom pool controller using a PLC which I might implement MQTT on. For the most part, the Insteon app has worked well for me (especially the new beta version), however as I add more non-insteon devices, I find myself wanting to combine the interface and interactions between insteon and non-insteon devices.
I have a new HA instance setup (I’ve tried a RPi 3 and a VM) and have the Insteon integration working (somewhat, it seems fairly unreliable and responses are very slow). I am currently using the 2245 hub and have read that there are issues with the hub vs the serial PLM.
I have also picked up a serial PLM (2413S) and an ISY994i off eBay cheaply, but haven’t done anything with them yet.
My question essentially is “what is going to be the most reliable and flexible system, given the hardware I have?”
In HA, I think it’s best to use the serial PLM instead of the Hub. Can both live on the same network at the same time? ie, can I keep the Hub active and use the Insteon app while HA uses the serial PLM interface?
If using the serial PLM in HA, does the addition of the ISY add any benefit? It seems that most of the functions in the ISY could be replicated in HA. Is the ISY integration for HA better or more reliable than direct to the serial PLM?
If adding the serial PLM in any scenario, will I need to start from scratch with all my Insteon devices and need to re-link all my existing 3-way switches?
Any advice appreciated!
