  • I have multiple zones: home and almost-home (same center coordinates, just larger diameter)

    This allows the house to “get ready” before someone is actually home, ie trigger lights to come on earlier.

    It also helps with random GPS jumps.

    Then, when the wifi connection is slow (maybe low phone battery) and people are literally outside the door, there’s no awkward pauses before someone actually “arrives”.

    I also have zones for our work places, intending to be used as a double-check, ie not-home isn’t usually good enough, I want the house to know we’re all at work and then the internal house cameras come on, etc.

    I also have a “visitors” flag, so that if friends / family are in and we leave, then the TV and lights don’t turn off and they’re not attacked by the laser robots…

    Also, (from memory) the person entity can be a combo of GPS and ping sensors to ensure it’s a correct reading

    That (2 FWs) was what I was considering initially.

    But, looking at some other posts, I’m starting to rethink my design as I only have 1 WAN connection, then I only need 1 FW (maybe). SIM would be rarely used, I’m not sure the overall cost would be worth it

    So separating FW from DHCP & DNS might be a better solution.






  • Good points there.

    For 1. The ISP router is a Fritz one set to bridge mode running over a PoE adapter from the same UPS the firewall is using. It stayed up all the time (looking back at the logs)

    1. Not sure what happened here, but the firewall is the DNS resolver and when everything else powered back up, nothing got an IP address. Now, whether thw service failed or the WAPs took longer to start than the devices could wait, I’m not sure, but as Scotty said: it’s dead Jim.

    2. Good point. I don’t need it ALL to be redundant.

    3. Also good. The UPS is directly connected to the firewall (which has NUT in), but it doesn’t inform anything else… I’ll look into that too.

    Nice mental reset for me about over thinking it… thanks





  • You can definitely change a sensor’s type, but my recommendation is to change it as close to the sensor as possible.

    I use zigbee2mqtt (so I don’t know if this applies to z-wave), but to change the 1 or 2 devices that were wrongly detected on my system, I changed them in zigbee2mqtt first and then HA will use the corrected data.

    If I corrected HA, then corrected zigbee2mqtt I’d have to do this twice, plus I presume HA wouldn’t automatically pick up any other changes I made to that sensor because it had been overridden.
