Sensors and Central unit on Ethernet, Modbus TCP/IP, BACnet - Hugo - 16.09.2020
I just start this trade, since I`m busy to find the right sensors solution for me.
Well, not that easy if you do not like the cloud and I'm also very picky about Sensors. In general, I have seen something around 200 euros or something that can be expanded in this price range after the initial purchase. So at least future expansion has to be less than 200 euros and of course, cheaper is always better but without compromising (runs and don't make me runing).
Will not start a new post but adjust the following part:
Version 23.01.2021 / no guarantee
Finally installed

Interesting:
- Standing alone Sensor without Central unit:
W-Lan or RJ-45 (Version dependent) example: Querx WLAN PT100 https://shop.egnite.de/media/pdf/df/e0/26/egnite_Querx_Manual_V5.pdf
- Gateway for several radio sensors / Large selection of sensors:
HD35APW Central unit with Ethernet + Modbus TCP
Sensor HD35: Design for inside and another outside Desing - Batteries may not be rechargeable and unique.
Delta OHM - https://www.deltaohm.com/en/wp-content/uploads/document/DeltaOHM-HD35-wireless-datalogger-manual-en.pdf
No longer pursued but maybe interesting for you. There are also no Ethernet + Modbus TCP Sensors in

ALTA Ethernet Gateway incl. POE MODBUS TCP Note: Difficult to see, but they may have recurring usage fee - Didn't get an offer without an annual fee. Setup may needs a online Platform. However, there is also a "Monnit Serial Modbus for GatewayRS-232C / RS-485" Same model sold also under KWJ WSN Ethernet Gateway, KWJ WSN Ethernet Gateway, Alta Power, ION and and and...... but after the third, i do not more check in detail.

Did you check our LogicMachine Ambient?

Good to know and interesting but a single temperature doesn't help me. The LogicMachine Ambient becomes interesting for me as a back-up, when the LM becomes systemically relevant. Of course, two control units above are at the same price, but they read more than one temp. sensors which are cheaper than your unit and at least one of the two units can may communicate very clearly with the LM without a cloud. Additionally this two units are already used professionally in tricky situations, so they are even more than a semiprofessional sensor solution.
However, Co2 Sensors are expensive, so the LogicMachine Ambient is possibly even a free back-up for a LogicMachine light or the better first choice - is there really a Co2 sensor in? Whereby Co2 sensors probably cost more than 500 euros and are to calibrated annually.
