I understand that development is not always an easy job. However I consider really important that Opener compatibility gets improved with a constant rate. Surely enough necessities are different for every country but Elvox Vimar two wire intercom is really becoming very popular in Italy. Unfortunately (or luckily) my apartment block will change outdated urmet unit and will install the Elvox Vimar. I am so afraid I will have to do without my opener, one of the most useful devices I own!!
