I would like to drive an electric car and my interest was strongly increased by a lease offer from mijndomein (E399/month on a two year contract). This seems incredibly cheap for an E38.000 car, because the total costs would be E9576. Deducing some costs for insurance and the leasing company, expected deprecation would be roughly E8000 or 21% in two years. This seems rather low for an electric car, so I decided to scrape prices for second hand Nissan Leafs from autoscout24. I plotted the price versus age because most Leafs do not have all that much kilometers. I used requests to request the results, beautiful soup to extract the data and seaborn to visualize the results. The result is the following figure.
The figure shows that an effectively new Leaf is roughly E32.000. A really brand new one currently runs around E38.000, but these are mostly ex-demos and the like. After this initial deprecation (which is likely less than the discount the dealer gets), a linear approximation of the deprecation does not seem all that bad. The deprecation rate is then roughly E3700/month, closely resembling my estimation of the deprecation from the mijndomein lease deal.
Conclusion therefore, you might as well just buy one? Well, maybe. You would have to buy a Leaf at a roughly E6000 euro discount. Remarkably, a certain dealer is advertising with a E5000 discount, so that seems possible, and also seems to confirm the at least E6000 discount that dealers receive. Only thing is then that the risk of more deprecation is not for the lease company but for myself.
Finally, why is the discount so high, even for consumers. Well, it is widely believed that a 40kWh or even 45kWh Leaf (the current one is 30kWh) will arrive in January, boosting range to roughly 330/37km NEDC or 266/300 km of practical range, at the same price point. It is also rumored to have a less 'controversial' design. This will force discounts on current 30 kWh Leafs and therefore they are preferably sold before that announcement is made.
However, looking at the very short run time of the mijndomein deal, I thought that they will need an even larger discount to make that price work, so I would also not be surprised that the Leaf 2 will debut at the LA motorshow on November 15th. Consider that most car models run for 7 years and are then replaced and the current Leaf was introduced in 2010. Also consider that the Renault Zoe got a 41 kWh battery recently and now almost dwarfs the 250km range of the flagship product Leaf from the same company with a 400km range. If that introduction of the Leaf 2 happens with a 60kWh battery (as is assumed for the Leaf 2) at the current price point with deliveries starting in January, than Nissan would really crush the business case for all the 30kWh'ish current generation electric cars (BMW i3, Leaf, Zoe, Kia Soul, Hyundai Ioniq, e-Golf, etc.)! If we will only have the 45kWh upgrade, than it might still be worth the wait and discarding the current discounts, 50% range is very substantial and will put the Leaf at the front of the range battle again until the Chevy Bolt arrives. Exciting times ahead.

Domoticz support for the NAD 7050
I happen to have an NAD 7050 Direct Digital Network Amplifier. Great product, works well with my Spotify Premium account and using an optical connection as amplifier for my television audio signal. The sound quality with my Monitor Audio Bronze 5 speakers is excellent. The amplifier comes with an Android app to mainly set the volume. Sadly, the app stopped working with the release of Android Nougat. Now, I also happen to have a home automation system based on Domoticz to operate my Hue lights, my Daikin heat pump, my blinds and what not. So, I decided to add support for the NAD 7050 to Domoticz. The reason I could was that Tom Hartley tweeted that he had figured out how to control it. I used his code with some LUA glue and a bit of clicking in Domoticz. I detailed the procedure in the NAD 7050 Domoticz wiki entry and you can discuss it on the Domoticz forum topic.
