I was not willing to let go of my AHP until very recently; You may be able to do as I did: run both at same time… Yes, the naysayers here here YOU CAN’T DO THAT! STOP! BACKUP!! YOU WILL CAUSE ALL KINDS OF IRREPARABLE DAMAGE! NEVER, EVER, RUN TWO CM15’S AT ONCE!!!
I also do the impossible according to some: I run 3-4 TM751 transceivers to get RF sigs into my powerline from various locations around the 1000x1000’ area here with 3 separate buldings; gotta have one in the metal pole barn 800’ from everything else, and in RF deadspots I put em when needed.
I even do another major bad thinig according to some: I have V572RF32 receiver, with antenna on mast 30’ up, feedin my powerline.
Don’t mention the high power XTBR repeater to boost sigs and retransmit them across both phases of 230v here…
So for last almost year I have done so along with second HG cm15. My original AHP into its programmed CM15, and I added a second CM15 on HG. I did NOT remove my AHP programs from the running CM15. Yes, I get double and triple repeats. But HG is robust enough to not crash as it apparently used to.
So my point is you should be able to ease into adding this HG to your present functioning AHP system as I did - as long as you have a 2nd cm15. (you can still buy them on ebay etc fairlly cheap).
Then, as you get HG up and running, you can add each AHP macro one at a time. delete them in AHP as you go or just leave them duplicated as I have for a long time. If one does not do the macro, the other will! Eventually hopefully you will get to the point you can unplug the AHP cm15 as I have.
Without the broadlink Rm pro (or newer model), you cannot replace AHP if you use security. Now you can. My only negative is HG does not offer an equivalent to AHP F2 key (Activity Monitor). HG does have a downloadable file, and you can search thru all its minutiae and locate what was sent or received, but not real time. This is the only disadvantage I see. THAT said, I still have my AHP cm15 here; I may delete my programs out of it and let it turn on again, with no retransmits but just so I can go to it and check the activity monitor (F2)!
AHP had a cool feature built into timers, available if you click the view advanced layout: multiple sends of commands. In our case, this is an absolute necessity. X10 is not reliable without it. So I have learned to program my HG schedules (equiv to AHP timers) to send XC10 commands multiple times if really important. This would be a great feature for HG to add, but they have enough other more imoportant stuff to do so I would not even ask them - since I can get around it with crative programming.
Be prepared for the assaults on this thread, saying I did very bad things to get to a full HG system and retire AHP.
