[APP][Pro] whatwatt - Connect. Control. Contribute

Hi everyone, @Doekse ,

I’ve been running the WhatWatt Homey app for about a week now. see Landis and Gyr Smart meter (model E450) and Homey dongle
The device is connected via M-Bus to the L+G E450 and delivers stable data in both the manufacturer’s app and on their website.

In Homey, however, I’m experiencing dropouts:

  • Case a) After an internet outage (router restart required).

  • Case b) Without any obvious reason. This has become more reproducible since I created virtual devices for Phase 1, 2, and 3 (W).

Each time, restarting the WhatWatt app in Homey fixes the issue — but of course this isn’t ideal.

I also have some detailed charts:

  1. Router restart

  2. Created two Virtual Devices (using Device Capabilities)

  3. Another router restart

  4. “Random” data dropout


Why the Virtual Device? I created the virtual devices for Phase 1, 2, and 3 in order to:

  • monitor the load on each phase separately,

  • and have the separated total daily consumption for each.

Has anyone else seen this behavior, or found a way to keep the app stable without having to restart it manually?

Maybe A script to check sensor last update?

Thanks!
