Looking for some well priced door sensors. I heard the Xfinity / Comcast ones on ebay do well and also do temperature.

Anyone have any experience with them or know if anything better priced?

I've had good luck with this Zigbee one. It's on the larger side, but takes AAA batteries which is nice. THIRDREALITY Zigbee Door/Window Sensor

Alternatively, if you're keen to tinker a bit you can get an SDR and then use 433MHz sensors. (Requires using RTL_433 and MQTT).

I was able to use the existing sensors from my traditional security system this way. Nice thing is that it's the most reliable wireless components on my system and the battery lasts forever.

I would suggest a nooelec SDR like this one: Nooelec RTL-SDR v5 Bundle

And something like this for sensors: Door Magnetic Contact Sensor
