I have a prebuilt EmonEVSE that I had installed just before the ESP32 wifi modules were released (sigh). I’d like to enable TLS on the MQTT connection but I know that the ESP8266 module doesn’t have the resources to handle that, so I guess I’m looking to upgrade.
As far as I know, I’ll need to:
- Update the firmware on the OpenEVSE itself, currently running 5.1.0.T2. This can’t be done over the air, I believe, and I’ll need one of these.
- Remove the ESP8266 module and replace it with one of the ESP32 modules from the shop, which ought to be plug-and-play.
- Is this all correct? Anything I’ve missed out?
- I have no qualms about opening up the EmonEVSE to do this stuff, I’m an electronic engineer but I’d like to check that in doing so I won’t be voiding any warranties or doing anything that’s technically against any regulations?
Thanks a lot!
