I’m going to hope that 99122 is similar enough to Hunter 99120, and therefore a C2 template might work?
See this post.
Now, how to add a template remote to Bond Bridge without a physical remote to trigger the template?
There was an old post here I referenced to come up with this API command you could try in a command line / terminal of a computer on the same network as your Bridge:
curl -H "BOND-Token: aaaaaaaaaaaaaaaa" -i http://n.n.n.n/v2/devices/ -X POST -d "{\"template\":\"C2\",\"name\":\"Test C2\",\"properties\":{\"addr\":\"1111\",\"bps\":3000,\"zero_gap\":30,\"freq\":433920}}"
(make sure to modify the command above to reflect your BOND-Token and IP address)
The problem would be pairing to the receiver on your device seems like two buttons being held, not just one (like the first link I included above)… So even if the template is added and correct, it might be for naught if you can’t pair it.
Thought about buying a replacement remote, at least for a day?
