Can you use multiple transformers in one yard?

in-lite transformers can be combined. The SPLITTER can be used to connect one light sensor to multiple transformers and all lights will then switch on at the same time. Note: It is not possible to connect a single light sensor if you want to use the HUB transformer together with a CB transformer. The SMART HUB-150 transformers do not have a light sensor, but use an astronomical clock. If you want to use both the SMART HUB-150 and a HUB-50/100 transformer in your yard, you will need to operate the HUB-50/100 using the touch panel on the transformer.
