Hi!
I hade an old Telldus system that i upgraded to Homey. I have an Telldus weatherstation that operates with 433 MHz.
I have noticed that it drains a lot of battery… The summer was ok because the weatherstation also has a solarpanel. But now in the autumn the battery lasted a week!! Does anyone have a solution?
Or in worst case some other weatherstation that has following sensors, temperature, rain, wind and also has an indoor display?
Make sure you use good batteries. The manual of my weather station (Alecto WS-5500) suggested using AA lithium batteries, which are much more resilient to hot and cold temperatures than regular alkaline batteries. They also store more power (I installed my weather station about 18 months ago and haven’t yet had to replace batteries).
Thank´s! I will try that 
And it is not the Homey draining the batteries… 
As it is 433 MHZ it is oneway, so nothing is sent from the Homey to the sensors.

I would not use lithium batteries in a unit that has a solar panel charging system.
I also have a Telldus weather station and used alkaline batteries in it for a few years which was fine. However, the temp/humidity sensor stopped reporting so I took the whole unit down from the roof to check. I found some corrosion and two PCB traces that was broken so I fixed that and put IKEA rechargeable batteries in it instead. It feels much better to have batteries that are ment to be charged in a unit that has a charging function.
(By the way…the corrosion was not due to leaking batteries. It was just poor sealing and cheap materials.)
And as Anders wrote above…Homey can never drain the batteries from a 433 MHz unit. 433 MHz units are not even aware Homey exists, or anything else for that matter, they are transmitting in the blind.
