I have been testing a small Smartthings environment (5 zigbee devices and 7 zwave devices) for the past few months in anticipation of using a bigger system in a home I am building. So far everything has been working fabulously.
I have found that I prefer to use the Ecolink sensors as opposed to the smartthings motion sensor / door sensors primarily because they are quite a bit cheaper, and second because I am finding the Ecolink motion sensor has much better battery life and works better outdoors than the smartthings motion sensor (both v1 and v2). For example, I have had a smartthings motion sensor (v2) and ecolink pir sitting outside for about 2 months. The smartsense battery is now at 66% with the cold snap we are having. It is also extremely sensitive which doesn’t bode well outdoors. The ecolink is at 99% battery and if set to Pet2 sensitivity works pretty well as far as false positives with respect to blowing trees.
In the new home I will have over 200 zwave devices that will consist of Ecolink motion sensors, ecolink door sensors and linear wall switches. I’m about to pull the trigger on ordering the devices. Will this high number of zwave devices cause any issues (lag, anything else?) with smartthings?
