Static DHCP Leases not working for one host

Hi,

It seems like the new static dhcp lease (configured in the LCUI under Network / DHCP/DNS I enter are ignored. In my current setup, I’ve got two static dhcp leases, those were added over 2 years ago, both works just fine. Today I tried adding a a third entry. The new entry is a RPI, but no matter what I do, the device keeps on getting a DHCP address from the scope rather than the static entry configured.

These are the 3 last entries from /etc/config/dhcp, the two first ones work just fine.

config host
option name ‘nova’
option mac ‘38:2c:4a:6e:15:a7’
option leasetime ‘24h’
option ip ‘192.168.1.2’

config host
option name ‘backup’
option mac ‘00:11:32:54:2e:27’
option ip ‘192.168.1.133’
option leasetime ‘24h’

config host
option name ‘temperature’
option mac ‘b8:27:eb:83:99:f9’
option ip ‘192.168.1.11’
option leasetime ‘12h’

I’ve tried changing leasing times, I’ve tried releasing ip’s, I even waited until the lease expired and then tried again. I’ve tried removing lease files, both on the RPI and on the Turris.

From /var/log/messages as the device connected today after waiting 12h for the lease to expire:

Any ideas?

Sorry for basic stupid question but “have you tried to turn it off and on again?” - I mean DHCP service (and maybe also RPi) after config change - (I assume that you did but you did not mentioned it in your post). Apart from that I have no idea. Just yesterday I’ve configured static IP lease for my RPi on TO via Luci and it worked normally
