I am a happy user of the RFXtrx433E plugin 1.6.3 with latest firmware 235.
I used to have the RFXLan as well when running HS3 PRO from HomeSeer but I am in the process of completely switching over my home automation setup from PC and HS3 PRO into Macintosh world and run Indigo. I have found Indigo to be far better and easier to use and during my first test week I have even been able to produce some cool energy, temp/humidity and rain/wind charts which I was never able to do in HS3 PRO during my 12 months of testing...
I did notice though that the RFXLan has better receiver sensivity than RFXtrx433E but using an external antenna (yes I know it is not certified for it) made it possible for me to receive signals from ALL my sensors into my lab (even the ones in my garage 20-30 meters away). I live in a 5 year old house that is built with leca blocks (in ALL walls, not just the outer walls) and with a metal shield/bottom between the upper level and ground level (due to water based floor heating on the top floor as well). Talk about living in a Faradays cage...
Anyway, I am now using the RFXtrx433E and have so far enabled only the Oregon Scientific and AC protocols (yes I now AC and other similar protocols are bad and create a LOT of RF traffic, especially for example the door sensor as well as the motion sensor).
In HS3 PRO I was able to get the battery status into the web gui but I have not been able to see the battery status even in the Indigo event log and not in the Indigo web gui. I guess the plugin does not support it yet? I found some older threads in the forum that it seems that the battery status has been available in earlier versions of Indigo?
Would it also be possible to get the signal level number (that I can see in RFXmanager) into Indigo? It would be very good at least in the installation phase to see signal quality from the sensors being used.
