Identifying the P1 port
The P1 port is easily identifiable, usually labeled as such, and has an RJ12 plug size. If your meter has "DSMR" or "ESMR," it is supported, though this may not always be visible.
Some devices use the same RJ12 connector for different protocols. If the labels "RS485," "Modbus," or "M-bus" appear on the port, it is not supported.
Compatibility
When ordering the Homey Energy Dongle, you can be confident it is compatible with your P1 smart meter. We're committed to ensuring that all P1 smart meters with an RJ12 connector work with the Homey Energy Dongle.
In the unlikely event your specific P1 smart meter turns out to be incompatible, we will work to add support for it within two weeks or else provide you with a full refund. So you can always order with peace of mind.
Encryption
In Luxembourg, Austria, and Sweden, your energy provider might encrypt the smart meter's data. Therefore, Homey needs a decryption key to access the data during the Homey Energy Dongle's setup.
You can request the decryption key from your energy provider. The process varies by provider, but you will generally need to email them your address and smart meter serial number.
RJ45 HAN port
The Homey Energy Dongle works with smart meters that have a P1 port that use an RJ12 connector. It won't be compatible if your meter features a HAN port with an RJ45 connector.
