As outlined in previous posts I’m very interested in coming up with DIY or low-cost alternatives to the various Texecom communicators and accessories. I’ve been quite happy with my ComIP solution and my panel is connected to the wired network in the house. Since I bought mine Texecom have brought out a Wifi module, unsurprisingly named ‘ComWifi’:
This is sold significantly cheaper than the ComIP for some reason (about £50) even though it looks rather more complicated. Also, I do wonder slightly about the wisdom of mountinga Wifi module inside a metal box. Some enterprising ebayers have picked up on this as well and are selling custom enclosures:
I have heard from someone who has succeeded in building their own version of this, taking a big hint from the labelling on the official product – ‘USR-WIFI232-G2 UART to WiFi’. Sure enough this part can be obtained from the usual sources (Chinese sellers via eBay or other places) for little cost (about £7 although there do seem to be different versions out there).
The schematic above shows the G2 variant although there are others (including S and T) but I’m not quite sure what the differences are.
My correspondent has made this up into a board and installed it in the housing:
There is a certain amount of work needed to configure the module, which is done via a web interface:
Overall a very nice job!
There are similar such interfaces for wired ethernet as well, so you could do the ComIP DIY interface using one of these if you didn’t have a computer to hand to run ser2net on.
I’d be interested to hear of any other experiences.
