155855f02d02b01d254053885ec0610 shifted is 2ab0abe05a05603a4a80a710bd80c200which decoded is 0ed5075aa007070000370107000031 -- the beacon has the same pattern but we don't know what the field values are.

[AkaBoing]

a second device is on the way.
then we know more.
thx Christian.

for me its good to know: there is NO Channel !
zx7716 Monitor:
Select "Station", then "SET, now start zx7717 Meter and within 5 Seconds its the new Station (1-6).
unknown_2 hast another meaning.
we will see.

One of the yet unknown codes looks very good

not very usefull, but there is a beacon counter which increments +1 every 10 mins
the Monitor 7716 has Energy Management, so mb. the counter is used for this.

[zuckschwerdt]

And the counter is in two places. With the known little-endian encoding this could be:
time : 2025-01-02 22:52:26 Beacon : 0e d507 5aa0 07 3b00 00 3701 3a00 00 98

If 0x0034 = 52 (= 260 mins) is a cold start, then maybe did you run this sensor for 260 minutes so far? I guess you had it running for days. Will be interesting to see where the new meter starts!

[AkaBoing]

The meter takes only 0.6 Watt total so its running day and night. 260mins- sure but some coldstarts
In between to get usable beacon data.
the new sensor gets his own Phase to control L1 and L3. L2 is Not findable..
Now its easy to find other msg lengths, i simply Change 0d>0e>11>12 and 1e
we will see.

[AkaBoing]

i have no clue where to find an entry for "50Hz", 0x32 or similar with the given messages..
any ideas ?

[zuckschwerdt]

There might be more digits, 50.0 or 50.00 which would be around f401 or 8813. Or it could just be a flag for 50/60.

[AkaBoing]

There are some cheap solar Stations for car use which, Not connected to an extern net, gives 45, 47,50, even 55 Hz.
This might be a Chance to get this Unknown flag-value or whatever..
edit: i Just viewed all my logs for 0x13, found some but Not plausible..
We will see.

[AkaBoing]

the new meter with the ID 0x7e05 (Dezimal 1406)
has a much lower radiaton power.
also the beacon is sendet all 10mins
mb. older software release..

[AkaBoing]

Revolt zx7717 sends on 433Mhz !! ( +-100k)
so, if u hop to 866Mhz with- s1024k , u have a problem. No solution yet..
