Hi all,
I have a Panasonic Intellibalance ERV, that has 2 possible switch configurations, one for on/off, and one for boost.
The ERV was a retrofit so we never had a traditional box set up with a line and neutral.
I don’t need a physical switch, just something to control digitally through HA.
It seems like a dry contact relay switch could be a good option, and it can be powered separately by a 5V usb, which I can get from a nearby outlet.
Thanks!
Scott
