Models with 9V battery (replaceable)
Ei605-D / wired networking: NO / wireless networking included: No / Optional wireless module: No
Ei605C-D / wired networking: Yes / wireless networking included: Yes / Optional wireless module: Ei605MRF-D
Ei 605W-D / wired networking: No / wireless networking included: Yes / Optional wireless module: Ei605MRF-D
Models with 10-year lithium battery integrated
Ei605TY-D / wired networking: No / wireless networking included: No / Optional wireless module: No
Ei605TYC-D / wired networking: Yes / wireless networking included: Yes / Optional wireless module: Ei605MTYRF-D
Ei605TYW-D / wired networking: No / wireless networking included: Yes / Optional wireless module: Ei605MTYRF-D
The delivered here Ei605C-D is therefore - contrary to the product description - without 10-year lithium battery!
Otherwise, the device makes a very high-quality impression. The wireless networking and wire networking I have not tested.
For the supplied alkaline 9V battery a service life of over 1 year is given. Alternatively, you can also install a 9V lithium battery which should last as long as 2-3 times then.
