Hi,
I have a dimmer 2 and I tried, I think, all possibilities to upgrade the firmware without any success. Currently it is on 1.8.0.
See below message after an unsuccessful upgrade attempt.
{"status":"updating","has_update":false,"new_version":"20200904-094614/v1.8.4@699b08ac","old_version":"20200812-092210/v1.8.0@8acf41b0"}Any suggestions?
Thanks,
Dan
Hi,
have you tested our firmware archive too? 
Hi Stefan,
I have tried to downgrade using the archive but same result....it doesn’t seem to respond to either upgrade or downgrade. I also tried to factory reset it but still nothing. The device is working ok, but still not being able to upgrade is not great.
Any suggestions?
Thanks,
Dan
I have the same issue. Have you been able to find a solution? OTA gives me the following, where I don't even see a firmware version I can recognize. This is how I received the unit.
{"status":"unknown","has_update":false,"new_version":"","old_version":"20200528-111028/1026-new-device-dimmer-l@98d7122e"}Can this thread be marked as unresolved? I believe there has not been a solution proposed to the problem. Thanks.
