I just SSH’d in to the USG gateway, and also pinged it from there as well, so it would show up in the Wireshark trace. In the trace, I can show you that the owner of .250 is the Rachio based on the MAC address. If I change the filter from eth.addr == x to ip.addr == 192.168.10.50, after the DHCP traffic, I only see IGMPv2 traffic. (and the ICMP traffic from the USG, since I pinged it from there.)
