I didn’t want to use the relay board because I have to connect 230V completely and I don’t think these relays without housing are completely harmless, especially if there are children in the house.
There is the possibility to switch radio sockets per 433MHz but the safer one. Since all live parts are then also cleanly processed.
What do you mean with a repeater via Wemos? So single stations with 433MHz receiver and transmitter to carry the signal? I think this is very susceptible to interference, or have you had other experiences?
I found the power supply of the NodeMCU via Micro USB quite good. They provide enough power for the sensors and the 433MHz transmitters. I wanted to solder it all and install it in a surface mounted junction box.
The MQTT sensor query of the 3 nodes is spinning around since this morning and I can’t do anything with the error. At the same time Pimatic shows the following error:
error [pimatic]: Error loading device “nmcu3”: (@plugin.brokers[@config.brokerId])
error [pimatic]: Error loading device “nmcu2”: (@plugin.brokers[@config.brokerId])
error [pimatic]: Error loading device “nmcu1-temp-tiefland”: (@plugin.brokers[@config.brokerId])
A restart of Mosquitto, Pimatic and finally the whole Pi didn’t make any difference.
The error occurred at 11:27 this morning. The last 2 days, however, no changes were made at the configuration.
