Is there an alternate controller for the SA-4? I've been through three and have been unable to get them to connect or to hold a charge. While hawaiian hot weather may have an impact, I'm seeking an alternate solution.
Neither the SA-4 or the SA-5 have a 3rd party system integration port, so if you could see how your friends system is configured, and get the same remote, you might be in business. Let us know if this is possible, I am interested as well. Thank you.
