The FTW software's license is at https://github.com/srcfl/ftw/blob/master/LICENSE.
FTW uses AGPL v3 only with a narrow Energyplan combination permission.
The proprietary Energyplan worker has separate household-use terms.
Commercial use and distribution of that worker require a Sourceful agreement.
The proprietary Energyplan worker allows unmodified use with FTW only for a
person's own private household. Free, noncommercial redistribution with FTW
is allowed only for that household use, with the binary license and
third-party notices. Other use or distribution requires a separate written
Sourceful license, including commercial use, resale, paid installation/support
and hosted or managed operation for others. These limits do not apply to
FTW's AGPL-covered code.
Earlier software versions retain their earlier grants.

References to FTW's software license on this website describe the product.
