All newer INSTEON modules shipping since March 2012 have the i2CS firmware, which includes many reliability improvements.

However, the extensive Indigo changes required for the i2CS firmware compatibility are only available in Indigo 5 and higher. You can download the latest version of Indigo here. Note that all major version upgrades to Indigo are paid upgrades, but upgrade discounts are available. To upgrade visit our purchase page and enter your current registration code and we'll show your specific upgrade discount eligibility. You can also register for a free 30 day trial of the latest version of Indigo to make sure it supports all of your INSTEON modules.

Additionally, i2CS firwmare modules now require INSTEON extended messages to be fully configured and the older PowerLinc 2414U does not support extended messages.

The i2CS modules work with the newer PowerLinc interfaces, including:

• PowerLinc 2413U (Dual-Band – recommended)
• INSTEON RF Adapter (RF Only – discontinued)

Note: Smarthome no longer makes a standalone controller like the 2414U that Indigo can use. See our article on standalone controllers for more details.
