Comment (by toralf):

 In the mean while I do have this
 {{{

 @daily   [[ $(/opt/torutils/key-expires.py
 /var/lib/tor/data/keys/ed25519_signing_cert)  -lt 864000 ]] && echo "Tor
 key is expiring soon"
 @daily   [[ $(/opt/torutils/key-expires.py
 /var/lib/tor/data2/keys/ed25519_signing_cert) -lt 864000 ]] && echo "Tor2
 key is expiring soon"

 # cat /opt/torutils/key-expires.py
 #!/usr/bin/env python3

 # put out the time (in seconds) before the key expires

 import codecs
 import sys
 import time

 # eg.: /var/lib/tor/data2/keys/ed25519_signing_cert
 #
 with open(sys.argv[1], 'rb') as f:
     cert = f.read()
     expire = int(codecs.encode(cert[35:38], 'hex'), 16) * 3600
     now = time.time()
     print(int(expire-now))
 }}}
 which does the job for me.
