no more ip address? therefore no more wifi monitoring...

Hm worked great for a few test runs just monitoring the pit temp.

went to do the same on my Thanksgiving turkey, and no IP address?

normally when i powered up the HM, it would display the address after a few seconds. i tried to log on, nothing at the address i always use. i try to restart the HM to see what address popped up...nothing?

i reloaded the software on the mSD card, but not really sure where to go from there? Do i need to reload the info on the card to the RPzeroW?

setup is a HM 4.2, RP zeroW.

Thanks for any help guys!

Check your WiFi access point (probably your firewall device) to see if your HM has registered and gotten a new/different DHCP lease. Hook up an HDMI cable and monitor to watch the rPi output & see what's going on under the covers.

Have you changed your WiFi configuration? New SSID? Passphrase? Security?

From your home network open a browser and point to http://heatermeter.com/devices/
This will help if you missed the IP when it flashed on the LCD.
Is your HM using wifi or hard wired?
